Opentype Specification Checks

Validates subfamilyNameID and postScriptNameID for the default instance record

Check ID: opentype/varfont/valid_default_instance_nameids
🔥 NotoSerifEthiopic[wdth,wght].ttf
  • 🔥 FAIL

    Thin instance has the same coordinates as the default instance; its subfamily name should be Light .

    Note: It is alternatively possible that Name ID 17 is incorrect, and should be set to the default instance subfamily name, Light , rather than 'Light '. If the default instance is Thin, NameID 17 is probably the problem.

    [code: invalid-default-instance-subfamily-name]
  • 🔥 FAIL

    Thin instance has the same coordinates as the default instance; its postscript name should be NotoSerifEthiopic-Light instead of NotoSerifEthiopic-Thin.

Check if each glyph has the recommended amount of contours.

Check ID: contour_count
⚠️ NotoSerifEthiopic[wdth,wght].ttf
  • ⚠️ WARN

    This check inspects the glyph outlines and detects the total number of contours in each of them. The expected values are inferred from the typical amounts of contours observed in a large collection of reference font families. The divergences listed below may simply indicate a significantly different design on some of your glyphs. On the other hand, some of these may flag actual bugs in the font such as glyphs mapped to an incorrect codepoint. Please consider reviewing the design and codepoint assignment of these to make sure they are correct.

    The following glyphs do not have the recommended number of contours:
    • uni1212 (U+04BC): found 3, expected one of: [1, 2]
