Description Behdad Esfahbod 2018-02-10 18:26:39 UTC 
As reported in:

  https://github.com/googlei18n/noto-emoji/issues/36#issuecomment-356954653

Looks like if a font is bitmap-only, and NO_HINTING is requested, we fail to load the glyphs.  Checking the code I see that is indeed the case in the FcPattern codepath:


↦       /* Force embedded bitmaps off if no hinting requested */ 
↦       if (ft_options.base.hint_style == CAIRO_HINT_STYLE_NONE) 
↦         bitmap = FcFalse; 
 
↦       if (!bitmap) 
↦           ft_options.load_flags |= FT_LOAD_NO_BITMAP; 

The fact that it's only done in that codepath is arbitrary to begin with.  Probably need to move somewhere closer to the actual glyph loading, and excepted if the FT_Face has no outlines.
