Indic glyphs naming not following recommendation

[mitradranirban]

The Devanagari glyphs are named like 'ka-deva'. However this naming scheme fails fontbakery as recommendation says "A glyph name must be entirely comprised of characters from the following set: A-Z a-z 0-9 .(period) (underscore). A glyph name must not start with a digit or period. There are a few exceptions such as the special glyph ".notdef"."
So the glyphs should be named like "ka_deva" to pass the tests.

You need to apply "production names" when building the font. The details for this are not yet accessible from Fontra, but fontmake's default rules work pretty well: fontmake --production-names ...

Thanks for clearing. However renaming the glyphs as a_deva, aa_deva etc would have helped creating fonts through automated means like github actions in google font workflow

Applying production names should be standard in such an environment. This naming convention comes from Glyphs app, which is also widely used in Google Fonts circles.
