Iosevka Custom build plan

This build plan includes only glyphs U+0000-036F to reduce the filesize of font files (which are much larger than normal for the web, but I really like it).

Font files are stored as public assets with a custom stylesheet for loading.

Usage

To rebuild the font files for any reason, replicate the process:

1. Import/customise as necessary
2. Make any further changes by hand in the generated TOML
3. Install the Iosevka repository and dependencies, using the instructions in the link above
4. Execute npm run build webfont-unhinted::IosevkaCustom
5. Execute cp dist/IosevkaCustom/WOFF2-Unhinted/*.woff2 <project-root>/public/assets/IosevkaCustom@30.3.0

When excluding glyphs, codepoints.net is a helpful reference. Convert the hexadecimal values to decimal for use in TOML.

Note: the font directory is named for the latest version at the time of writing and should be updated as applicable if the font files are rebuilt in future.

Issues

This solution is work in progress, mainly because font files are quite large. I have already taken some steps to reduce client-side impact:

• Removed glyphs outside the main latin range, since I don't use them
• Used unhinted font files, which causes console warnings (downloadable font: maxp: Bad maxZones: 0) but reduces file size noticeably
• Deferred loading font stylesheet to prioritise other resources

There may be opportunity for further optimisation, but for now I'm happy especially since all other resources are so lightweight.
