Hi Thomas,
Thanks for sending the original font file to me. The font contains invalid character mappings. FontCreator automatically removes invalid mappings, in your case both Gbreve and gbreve. You can fix this by adding correct mappings to these glyphs as described here:
How to enable a glyph, so it can be used as a character?
FontCreator also detected issues with the kerning data and stopped parsing the kerning data as soon as it detected corrupt data. There are numerous other technical issues with the font that might cause unexpected problems. Do let me know if this information helps.
And wouldn’t it be nice to inform the user that some information is lost due to the tables and hinting?
Such a warning is on the to-do list for a long time, but I have mixed feelings about implementing it.
I will try CacheTT and report.
Perfect, I’m very curious about your findings.
