The ccmp feature is in the source glyphspackage but isn’t in the release TTFs.

• Some of the ligature stacking combining marks are not working but for this to work fully other things would be needed.
• The ccmp lookup for the softdotted substitution of i and j by idotless and jdotless should be in the TTFs, but dotless or decomposition of iogonek and istroke would also be needed.
• Case variants are not working but for this to work fully other things would be needed.

I think at least the softdotted lookup should be enabled as is for Dutch (or with dotless iogonek for Navajo and dotless istroke for others).

The current line-height feels a bit too large and the vertical centering of characters looks off.

Left is what I would consider correct line-height and character alignment (done with adjustments in the terminal), while right is how it looks by default. Both at 11pt.

Hello again, the variable font is not correct. Some glyphs are missing the dot and others are incorrect, the 1 glyph issue has resurfaced as well. (#21)

Why are some of the glyphs pixelated?

Maybe the subfamily is incorrect or there is no style-linking.

The glyphs for U+2716 HEAVY MULTIPLICATION X and U+2717 BALLOT X are essentially identical. U+2716 should be heavier. U+2717 should look more handwritten and asymmetrical. The current U+2716 glyph would be appropriate for U+2715 MULTIPLICATION X.

In the variable font the 1 is not the same as the regular fonts.

I haven't been able to get this font to work well with Microsoft Visual Studio Code. Any ideas? Specifically, there is no syntax highlighting.

The glyph for U+1D7B LATIN SMALL CAPITAL LETTER I WITH STROKE instead looks like a dotless ⟨i⟩ with stroke.

I'm not sure exactly how to phrase this, but have a look at this image and notice that three glyphs are much more pixelated than their “siblings”.

I don't remember seeing this issue with other fonts. On the other hand, termite seems to render this just fine.

Is there additional information that I can provide? Any experiments that I could make?
