Google Fonts 2016 Glyph Sets

Three levels of glyph sets were developed in June 2016 as a new baseline standard for fonts in the Google Fonts library. Exising fonts in the library can be upgraded to these as part of a drive towards new quality standards. All new fonts submitted to the library must now support the Plus level as a minumum requirement.

Three sets are available in this directory: Plus, Pro and Expert.

Glyphs App Tip

Inside [filter lists](filter lists) are text files with a list of glyphs for each set. Open Glyphs and in the left bottom sidebar, create a new list filter, and paste the contents of these TXT files to check if your fonts supports these characters. A ✓ will indicate you are all set. Otherwise ctrl + click on the numbers to generate missing glyphs.

N.B. If you get an error while creating new glyphs, select all glyphs in your font, from the top menu choose Glyph -> Update Glyph Info. Try again. If updating Glyph Info didn't work make sure [ ] Use custom naming is unckecked in Font Info > Other Settings. 

See TROUBLESHOOTING.md for more details.

Ligated Dutch IJ

In case your IJ diagraph is really ligated, or has a special form (like shortened I) you will need to add these glyphs: I_J.loclNLD i_j.loclNLD Iacute_J.loclNLD iacute_j.loclNLD. Glyphs (versions 2.3.1 or later) will automate the OT code. If your font includes small caps, make sure to add .sc glyphs too.
