Glyph name too long
Audit code: glyph-name-too-long
Definition
Glyph name exceeds 63 characters. The OpenType post-table v2 spec caps individual names at 63 bytes; longer names get silently truncated on export, which can then collide with whatever existing glyph already shares the prefix. Use the AGLFN suggestion chip in the glyph browser to get a canonical short name.
How Patens surfaces this
The Patens audit module checks for glyph-name-too-long across five teaching surfaces: the edit-panel inline issue list, the
project-wide audit page, the release pre-flight check, the family hub,
and the home-page project tile. Every surface shows the same plain-English
explanation and links back to this page. This rule is detection-only — there's no automatic fix because the
correction is design-dependent (it requires a judgment call about the
glyph's intended shape or the font's intended behaviour). The audit
message links to the specific glyph or field that needs attention.
Run this check yourself
Patens runs every audit rule live as you draw — including this one.
The editor (in private alpha) shows glyph-name-too-long firing on real
glyphs, or check your own work from the CLI:
