Fractions

[m-casanova]

I think numerators and denominators vertical positions should be consistent with fraction like /onehalf and /onequarter (and /fraction seems different too)

Also some fractions seem inconsistent (e.g. different denominator positions in /onehalf and /onequarter in Bold)

[m-casanova]

Probably numerators and denominators should be added instead of using superscript and subscript numbers

@m-casanova Thank you for the suggestions. I'll check the issue for the next version.

@StefanPeev I'm sorry. I was referring to fractions created with the opentype "frac" feature, which are inconsistent with built-in fractions (like /onehalf). Example in LibreOffice Writer:

"frac" feature uses superscript and subscript to create fractions, but I think numerators and denominators should be added. And /fraction should be modified to reflect built-in fractions.

Also the vertical position of numbers in built-in fractions should be checked (e.g. "2" in /onehalf seems slightly higher than "4" in /onequarter; see "8" in ⅛ ⅜ ⅝ ⅞)

@m-casanova New full functioning fraction feature is included in v.1.026.

@StefanPeev Sorry to annoy you again. In Italic (v. 1.026) numerators are like superscripts. Example with /onesuperior /one.numr /onehalf and overlapping /one.numr /onehalf

Also previously width was fixed (tabular) for superscripts and subscripts; now it's variable (proportional) for superscripts, numerators and denominators, while it's fixed for subscripts (Italic and BoldItalic). Personally I prefer fixed width numbers for tables, but I know that different fonts use different methods (e.g. Libertinus and Source Serif use fixed width, while STIX Two Text uses variable width).

Subscript numbers are not consistent with others subscripts

Also sups, numr, dnom and subs height seems inconsistent

[StefanPeev]

@m-casanova Superscript glyphs are a little bit higher then nomerator glyphs and the subscript glyphs are a little bit lower then denominator glyps. Denominators lay on baseline. Here are the pictures for the Normal styles.

Here are the pictures for the Italic styles.
