-pyftsubset -- OpenType font subsetter and optimizer
-
-  pyftsubset is an OpenType font subsetter and optimizer, based on fontTools.
-  It accepts any TT- or CFF-flavored OpenType (.otf or .ttf) or WOFF (.woff)
-  font file. The subsetted glyph set is based on the specified glyphs
-  or characters, and specified OpenType layout features.
-
-  The tool also performs some size-reducing optimizations, aimed for using
-  subset fonts as webfonts.  Individual optimizations can be enabled or
-  disabled, and are enabled by default when they are safe.
-
-Usage:
-  """+__usage__+"""
-
-  At least one glyph or one of --gids, --gids-file, --glyphs, --glyphs-file,
-  --text, --text-file, --unicodes, or --unicodes-file, must be specified.
-
-Arguments:
-  font-file
-    The input font file.
-  glyph
-    Specify one or more glyph identifiers to include in the subset. Must be
-    PS glyph names, or the special string '*' to keep the entire glyph set.
-
-Initial glyph set specification:
-  These options populate the initial glyph set. Same option can appear
-  multiple times, and the results are accummulated.
-  --gids=<NNN>[,<NNN>...]
-      Specify comma/whitespace-separated list of glyph IDs or ranges as
-      decimal numbers.  For example, --gids=10-12,14 adds glyphs with
-      numbers 10, 11, 12, and 14.
-  --gids-file=<path>
-      Like --gids but reads from a file. Anything after a '#' on any line
-      is ignored as comments.
-  --glyphs=<glyphname>[,<glyphname>...]
-      Specify comma/whitespace-separated PS glyph names to add to the subset.
-      Note that only PS glyph names are accepted, not gidNNN, U+XXXX, etc
-      that are accepted on the command line.  The special string '*' wil keep
-      the entire glyph set.
-  --glyphs-file=<path>
-      Like --glyphs but reads from a file. Anything after a '#' on any line
-      is ignored as comments.
-  --text=<text>
-      Specify characters to include in the subset, as UTF-8 string.
-  --text-file=<path>
-      Like --text but reads from a file. Newline character are not added to
-      the subset.
-  --unicodes=<XXXX>[,<XXXX>...]
-      Specify comma/whitespace-separated list of Unicode codepoints or
-      ranges as hex numbers, optionally prefixed with 'U+', 'u', etc.
-      For example, --unicodes=41-5a,61-7a adds ASCII letters, so does
-      the more verbose --unicodes=U+0041-005A,U+0061-007A.
-      The special strings '*' will choose all Unicode characters mapped
-      by the font.
-  --unicodes-file=<path>
-      Like --unicodes, but reads from a file. Anything after a '#' on any
-      line in the file is ignored as comments.
-  --ignore-missing-glyphs
-      Do not fail if some requested glyphs or gids are not available in
-      the font.
-  --no-ignore-missing-glyphs
-      Stop and fail if some requested glyphs or gids are not available
-      in the font. [default]
-  --ignore-missing-unicodes [default]
-      Do not fail if some requested Unicode characters (including those
-      indirectly specified using --text or --text-file) are not available
-      in the font.
-  --no-ignore-missing-unicodes
-      Stop and fail if some requested Unicode characters are not available
-      in the font.
-      Note the default discrepancy between ignoring missing glyphs versus
-      unicodes.  This is for historical reasons and in the future
-      --no-ignore-missing-unicodes might become default.
-
-Other options:
-  For the other options listed below, to see the current value of the option,
-  pass a value of '?' to it, with or without a '='.
-  Examples:
-    $ pyftsubset --glyph-names?
-    Current setting for 'glyph-names' is: False
-    $ ./pyftsubset --name-IDs=?
-    Current setting for 'name-IDs' is: [1, 2]
-    $ ./pyftsubset --hinting? --no-hinting --hinting?
-    Current setting for 'hinting' is: True
-    Current setting for 'hinting' is: False
-
-Output options:
-  --output-file=<path>
-      The output font file. If not specified, the subsetted font
-      will be saved in as font-file.subset.
-  --flavor=<type>
-      Specify flavor of output font file. May be 'woff' or 'woff2'.
-      Note that WOFF2 requires the Brotli Python extension, available
-      at https://github.com/google/brotli
-
-Glyph set expansion:
-  These options control how additional glyphs are added to the subset.
-  --notdef-glyph
-      Add the '.notdef' glyph to the subset (ie, keep it). [default]
-  --no-notdef-glyph
-      Drop the '.notdef' glyph unless specified in the glyph set. This
-      saves a few bytes, but is not possible for Postscript-flavored
-      fonts, as those require '.notdef'. For TrueType-flavored fonts,
-      this works fine as long as no unsupported glyphs are requested
-      from the font.
-  --notdef-outline
-      Keep the outline of '.notdef' glyph. The '.notdef' glyph outline is
-      used when glyphs not supported by the font are to be shown. It is not
-      needed otherwise.
-  --no-notdef-outline
-      When including a '.notdef' glyph, remove its outline. This saves
-      a few bytes. [default]
-  --recommended-glyphs
-      Add glyphs 0, 1, 2, and 3 to the subset, as recommended for
-      TrueType-flavored fonts: '.notdef', 'NULL' or '.null', 'CR', 'space'.
-      Some legacy software might require this, but no modern system does.
-  --no-recommended-glyphs
-      Do not add glyphs 0, 1, 2, and 3 to the subset, unless specified in
-      glyph set. [default]
-  --layout-features[+|-]=<feature>[,<feature>...]
-      Specify (=), add to (+=) or exclude from (-=) the comma-separated
-      set of OpenType layout feature tags that will be preserved.
-      Glyph variants used by the preserved features are added to the
-      specified subset glyph set. By default, 'calt', 'ccmp', 'clig', 'curs',
-      'kern', 'liga', 'locl', 'mark', 'mkmk', 'rclt', 'rlig' and all features
-      required for script shaping are preserved. To see the full list, try
-      '--layout-features=?'. Use '*' to keep all features.
-      Multiple --layout-features options can be provided if necessary.
-      Examples:
-        --layout-features+=onum,pnum,ss01
-            * Keep the default set of features and 'onum', 'pnum', 'ss01'.
-        --layout-features-='mark','mkmk'
-            * Keep the default set of features but drop 'mark' and 'mkmk'.
-        --layout-features='kern'
-            * Only keep the 'kern' feature, drop all others.
-        --layout-features=''
-            * Drop all features.
-        --layout-features='*'
-            * Keep all features.
-        --layout-features+=aalt --layout-features-=vrt2
-            * Keep default set of features plus 'aalt', but drop 'vrt2'.
-
-Hinting options:
-  --hinting
-      Keep hinting [default]
-  --no-hinting
-      Drop glyph-specific hinting and font-wide hinting tables, as well
-      as remove hinting-related bits and pieces from other tables (eg. GPOS).
-      See --hinting-tables for list of tables that are dropped by default.
-      Instructions and hints are stripped from 'glyf' and 'CFF ' tables
-      respectively. This produces (sometimes up to 30%) smaller fonts that
-      are suitable for extremely high-resolution systems, like high-end
-      mobile devices and retina displays.
-      XXX Note: Currently there is a known bug in 'CFF ' hint stripping that
-      might make the font unusable as a webfont as they will be rejected by
-      OpenType Sanitizer used in common browsers. For more information see:
-      https://github.com/behdad/fonttools/issues/144
-      The --desubroutinize options works around that bug.
-
-Optimization options:
-  --desubroutinize
-      Remove CFF use of subroutinizes.  Subroutinization is a way to make CFF
-      fonts smaller.  For small subsets however, desubroutinizing might make
-      the font smaller.  It has even been reported that desubroutinized CFF
-      fonts compress better (produce smaller output) WOFF and WOFF2 fonts.
-      Also see note under --no-hinting.
-  --no-desubroutinize [default]
-      Leave CFF subroutinizes as is, only throw away unused subroutinizes.
-
-Font table options:
-  --drop-tables[+|-]=<table>[,<table>...]
-      Specify (=), add to (+=) or exclude from (-=) the comma-separated
-      set of tables that will be be dropped.
-      By default, the following tables are dropped:
-      'BASE', 'JSTF', 'DSIG', 'EBDT', 'EBLC', 'EBSC', 'SVG ', 'PCLT', 'LTSH'
-      and Graphite tables: 'Feat', 'Glat', 'Gloc', 'Silf', 'Sill'
-      and color tables: 'CBLC', 'CBDT', 'sbix', 'COLR', 'CPAL'.
-      The tool will attempt to subset the remaining tables.
-      Examples:
-        --drop-tables-='SVG '
-            * Drop the default set of tables but keep 'SVG '.
-        --drop-tables+=GSUB
-            * Drop the default set of tables and 'GSUB'.
-        --drop-tables=DSIG
-            * Only drop the 'DSIG' table, keep all others.
-        --drop-tables=
-            * Keep all tables.
-  --no-subset-tables+=<table>[,<table>...]
-      Add to the set of tables that will not be subsetted.
-      By default, the following tables are included in this list, as
-      they do not need subsetting (ignore the fact that 'loca' is listed
-      here): 'gasp', 'head', 'hhea', 'maxp', 'vhea', 'OS/2', 'loca',
-      'name', 'cvt ', 'fpgm', 'prep', 'VMDX', and 'DSIG'. Tables that the tool
-      does not know how to subset and are not specified here will be dropped
-      from the font.
-      Example:
-         --no-subset-tables+=FFTM
-            * Keep 'FFTM' table in the font by preventing subsetting.
-  --hinting-tables[-]=<table>[,<table>...]
-      Specify (=), add to (+=) or exclude from (-=) the list of font-wide
-      hinting tables that will be dropped if --no-hinting is specified,
-      Examples:
-        --hinting-tables-='VDMX'
-            * Drop font-wide hinting tables except 'VDMX'.
-        --hinting-tables=''
-            * Keep all font-wide hinting tables (but strip hints from glyphs).
-  --legacy-kern
-      Keep TrueType 'kern' table even when OpenType 'GPOS' is available.
-  --no-legacy-kern
-      Drop TrueType 'kern' table if OpenType 'GPOS' is available. [default]
-
-Font naming options:
-  These options control what is retained in the 'name' table. For numerical
-  codes, see: http://www.microsoft.com/typography/otspec/name.htm
-  --name-IDs[+|-]=<nameID>[,<nameID>...]
-      Specify (=), add to (+=) or exclude from (-=) the set of 'name' table
-      entry nameIDs that will be preserved. By default only nameID 1 (Family)
-      and nameID 2 (Style) are preserved. Use '*' to keep all entries.
-      Examples:
-        --name-IDs+=0,4,6
-            * Also keep Copyright, Full name and PostScript name entry.
-        --name-IDs=''
-            * Drop all 'name' table entries.
-        --name-IDs='*'
-            * keep all 'name' table entries
-  --name-legacy
-      Keep legacy (non-Unicode) 'name' table entries (0.x, 1.x etc.).
-      XXX Note: This might be needed for some fonts that have no Unicode name
-      entires for English. See: https://github.com/behdad/fonttools/issues/146
-  --no-name-legacy
-      Drop legacy (non-Unicode) 'name' table entries [default]
-  --name-languages[+|-]=<langID>[,<langID>]
-      Specify (=), add to (+=) or exclude from (-=) the set of 'name' table
-      langIDs that will be preserved. By default only records with langID
-      0x0409 (English) are preserved. Use '*' to keep all langIDs.
-  --obfuscate-names
-      Make the font unusable as a system font by replacing name IDs 1, 2, 3, 4,
-      and 6 with dummy strings (it is still fully functional as webfont).
-
-Glyph naming and encoding options:
-  --glyph-names
-      Keep PS glyph names in TT-flavored fonts. In general glyph names are
-      not needed for correct use of the font. However, some PDF generators
-      and PDF viewers might rely on glyph names to extract Unicode text
-      from PDF documents.
-  --no-glyph-names
-      Drop PS glyph names in TT-flavored fonts, by using 'post' table
-      version 3.0. [default]
-  --legacy-cmap
-      Keep the legacy 'cmap' subtables (0.x, 1.x, 4.x etc.).
-  --no-legacy-cmap
-      Drop the legacy 'cmap' subtables. [default]
-  --symbol-cmap
-      Keep the 3.0 symbol 'cmap'.
-  --no-symbol-cmap
-      Drop the 3.0 symbol 'cmap'. [default]
-
-Other font-specific options:
-  --recalc-bounds
-      Recalculate font bounding boxes.
-  --no-recalc-bounds
-      Keep original font bounding boxes. This is faster and still safe
-      for all practical purposes. [default]
-  --recalc-timestamp
-      Set font 'modified' timestamp to current time.
-  --no-recalc-timestamp
-      Do not modify font 'modified' timestamp. [default]
-  --canonical-order
-      Order tables as recommended in the OpenType standard. This is not
-      required by the standard, nor by any known implementation.
-  --no-canonical-order
-      Keep original order of font tables. This is faster. [default]
-
-Application options:
-  --verbose
-      Display verbose information of the subsetting process.
-  --timing
-      Display detailed timing information of the subsetting process.
-  --xml
-      Display the TTX XML representation of subsetted font.
-
-Example:
-  Produce a subset containing the characters ' !"#$%' without performing
-  size-reducing optimizations:
-
-  $ pyftsubset font.ttf --unicodes="U+0020-0025" \\
-    --layout-features='*' --glyph-names --symbol-cmap --legacy-cmap \\
-    --notdef-glyph --notdef-outline --recommended-glyphs \\
-    --name-IDs='*' --name-legacy --name-languages='*'

-# Note:   When comparing block names, casing, whitespace, hyphens,
-#         and underbars are ignored.
-#         For example, "Latin Extended-A" and "latin extended a" are equivalent.
-#         For more information on the comparison of property values,
-#            see UAX #44: http://www.unicode.org/reports/tr44/
-#
-#  All block ranges start with a value where (cp MOD 16) = 0,
-#  and end with a value where (cp MOD 16) = 15. In other words,
-#  the last hexadecimal digit of the start of range is ...0
-#  and the last hexadecimal digit of the end of range is ...F.
-#  This constraint on block ranges guarantees that allocations
-#  are done in terms of whole columns, and that code chart display
-#  never involves splitting columns in the charts.
-#
-#  All code points not explicitly listed for Block
-#  have the value No_Block.
