Warns reported about kalnia-glaze HOT 7 CLOSED

When creating a variable font, the designer must make sure that corresponding paths have the same start points across masters, as well as that corresponding component shapes are placed in the same order within a glyph across masters. If this is not done, the glyph will not interpolate correctly.

Here we check for the presence of potential interpolation errors using the fontTools.varLib.interpolatable module.

• ⚠ WARN Interpolation issues were found in the font: - Contour order differs in glyph 'uni25CC': [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15] in <fontTools.ttLib.ttGlyphSet._TTGlyphSetGlyf object at 0x10b6b8190>, [15, 2, 4, 1, 6, 3, 8, 5, 10, 7, 12, 9, 14, 11, 0, 13] in <fontTools.ttLib.ttGlyphSet._TTGlyphSetGlyf object at 0x10b6ba8c0>.

It is a common practice to have math signs sharing the same width (preferably the same width as tabular figures accross the entire font family).

This probably comes from the will to avoid additional tabular math signs knowing that their design can easily share the same width.

• ⚠ WARN The most common width is 460 among a set of 5 math glyphs.
  The following math glyphs have a different width, though:

Width = 461:
plusminus, plus

Width = 364:
greaterequal, less, greater, lessequal

Width = 385:
multiply

Width = 652:
approxequal

Glyphs are either accessible directly through Unicode codepoints or through substitution rules.

In Color Fonts, glyphs are also referenced by the COLR table.

Any glyphs not accessible by either of these means are redundant and serve only to increase the font's file size.

• ⚠ WARN The following glyphs could not be reached by codepoint or substitution rules:

  • .notdef.color0

  • A.color0

  • AE.color0

  • Aacute.color0

  • Abreve.color0

  • Acircumflex.color0

  • Adieresis.color0

  • Agrave.color0

  • Amacron.color0

  • Aogonek.color0
