When com.google.fonts/check/whitespace_glyphs fails, the rationale text is:
The OpenType specification recommends that fonts should contain glyphs for
the following whitespace characters:
- U+0020 SPACE - U+00A0 NO-BREAK SPACE
The space character is required for text processing, and the no-break
space is useful to prevent line breaks at its position. It is also
recommended to have a glyph for the tab character (U+0009) and the soft
hyphen (U+00AD), but these are not mandatory.
This issue concerns U+00AD SOFT HYPHEN; the text of this rationale recommends having a glyph for U+00AD SOFT HYPHEN, but other checks and discussions recommend against including such a glyph.
Observed behaviour
When com.google.fonts/check/whitespace_glyphs fails, the rationale text is:
This issue concerns U+00AD SOFT HYPHEN; the text of this rationale recommends having a glyph for U+00AD SOFT HYPHEN, but other checks and discussions recommend against including such a glyph.
See com.google.fonts/check/soft_hyphen
(Describe the results you're getting)
Expected behaviour
Avoid mentioning U+00AD SOFT HYPHEN in the rationale of this check at all.
(though i note https://github.com/fonttools/fontbakery/issues/4095 has resulted in the rationale for com.google.fonts/check/soft_hyphen changing, that issue has not been closed)
Maybe we should also look into U+0009 CHARACTER TABULATION (from Unicode 1.0); i have no idea.
Resources and steps needed to reproduce
For example, remove
/uni00A0from a font and runfontbakery.
