Why is the name for uni02C9 firsttonechinese? This is the spacing macron character so is firsttonechinese an error?
The unicode name is
MODIFIER LETTER MACRON but the Adobe Glyph Library has it as
firsttonechinese is not Adobe’s recommended name for U+02C9 – note that 02C9 is not in Adobe Glyph List For New Fonts. Rather,
uni02C9 is the recommended name.
If a font uses
firsttonechinese for a glyph, some Adobe sofware will, if needed and no other info is available, assume U+02C9 was the underlying character (see the Adobe Glyph List).
The aglfn defines names for final fonts. And the glyph will get an uni-name on export. We are speaking about design time names.
