Hello,

Somewhere on Typophile I read about adding dots (nuqta) to base glyph in VOLT.
This means instead of making glyphs for each combination of base glyph with dots in FontLab, you use VOLT to compose glyphs on the fly using a single base glyph.

This has something to do with CCMP feature.

I request anyone who has used this feature for the mentioned purpose to kindly share their experience.

Thanks and regards.

Wondering if there is a plan for Fontlab to embody VOLT's features with next new version !

I'm trying to set up a contextual multiple substitution (one-to-many), but FOG 5 keeps choking on the feature file and won't generate a font. The same substitution works in VOLT for TrueType OpenType fonts, although the substitution works only in Microsoft programs, and not in Adobe programs.

In VOLT, I was able to set up the substitution as:

comma -> special_glyph comma -- when preceded by -- glyph_group

Now I'm trying to use it in a feature file (based on Adobe specs) for generating a CFF OpenType font in Fontographer 5.

Here's the basic syntax for an Adobe spec feature file:

sub [ @Glyphclass ] comma' by specialglyph comma;
