Something is wrong with Ohmsign-grek..

Post by RickDe » Mon Oct 19, 2020 5:46 pm

I'm having issues with some fonts when trying to copy characters from a regular it's Italic version in order to fix issues. My process is fix them in the regular, and then using the transformer to create the italic version.

Overall I'm having issues copying about 200 characters at a time and I think I've tracked my issue to Ohmsign-grek. If the font has this glyph it breaks the copy always at this character.

Also If I try and insert just this glyph, it will not add it. Saying "All of the glyph names allready exist in the font". I checked and they don't.

Even if i delete all glyphs in the font it still won't let me insert Ohmsign-grek

On a font with Ohmsign-grek, it will auto complete to 8486. If i remove the name it will auto complete the name from 8486.

I should also say that i've noticed that Multi-Mapped characters do not copy. I didn't mention this as I'm not sure if Multi-Mapped characters are valid.

Multi-mapped glyphs are certainly valid, and will save a few bytes in the size of the font, but you could also use composites instead. I do whenever I can to save space and reduce the work of editing glyphs. I rarely use multi-mapped glyphs.

Generate glyphnames from the Tools menu to make sure that your glyphs are correctly named.

Omega-grek is not the same as Letterlike Symbol Ohm-grek. Though the glyphs may often be identical, they can be different.

On a new font, File->New this issue exists.

via Insert->Glyphs paste in, Ohmsign-grek. Hit validate it will say that it is in the font, but it is not. Without validate it just does nothing when inserting, no character added.

via Insert->Characters, goto code point 8486, double click to add the character, hit ok. See that it added 8486 as "Ohmsign-grek"

Can you confirm this is a bug?

I remember now what the problem is. Any glyphname containing a hyphen requires quotes around it.

Ok Bhikkhu, I think it's a bug :D or as we developers call them. "Unintended features".

Copy Glyph should probably add quotes to the glyph name, or maybe validate could add the quotes to all names during the validation.

Out of curiosity why would a hyphen be special?

The hyphen can be used to define ranges, e.g. a-z, or 8486-8490.

Just uncheck "Ranges" and it should accept glyph names that contain a hyphen.

Wow... such a simple solution! I did not even see that checkbox.
