Regenerate (or delete) non-variable instance fonts because of font weight issues #301

Closed JNord03 closed 2 months ago

JNord03 commented 1 year ago

The 'w' glyph in both upper and lower case appears to have a higher weight (Medium) in the Regular font than the others. The same applies to numbers 2, 4, 7, 8, the question and exclamation marks and several more with diacritics. In the Medium font, 'w' looks like a single 'v'. In the Black font, 'w' appears lighter in color than the rest of the glyphs.

That is interesting. Looks like Windows has some problem with the font that I am not seeing on macOS, nor in Adobe apps.

@kateliev you are on Windows, can you take a look at this?

@tphinney looks like a hinting issue of some sort... will check it out

kateliev commented 1 year ago

@tphinney funny enough it is not... actually it is the font itself! But the problem does not reside in the source, it is just the instance generated?

Actually it seems that ALL of the instances exhibit the very same problem. They seem to be generated from source where /.notdef/two/four/seven/eight/W/exclam/question/w were incompatible. But in the current source they are perfectly fine! Which leads me to conclude that there was some export issue perhaps, back then when these were generated?

... and looking at all the TTF rises the following question - all of these fonts that reside in fonts/static/ are with 177 glyphs strong... but the source is 1234 glyphs. Are these subsets and why?

Oh! It is one of the old instance fonts! Yeah, those are ancient, haven't regenerated them in aeons. I suspect there was a problem in the variable source at the time, but fixed long ago.

JNord03 commented 1 year ago

Yes, the problem only occurs in the instances. I downloaded them because I was unable to access any weight other than Light using LibreOffice. The software supports some variable fonts, but apparently not all of them.

@tphinney do we actually have now fixed instance fonts? It kind of slipped my mind?

tphinney commented 2 months ago

Had them VERY EARLY in development. Need to either update them, or delete them, because they are way out of sync with the current variable fonts (with many more bugs).
