[Bug 932958] Re: Some characters too wide with default fixed-with font


In a terminal, enter:

    pango-view --font="Ubuntu Mono 48" --markup --text='<span

This demonstrates that:
- the ☺ character in Ubuntu Mono is the correct width
- the ▷ character is not present in Ubuntu Mono at all.

The lists of fonts that "have the problem, and ... do not" seem to be
lists of fonts that contain those two characters or not.

So the bug here probably is not with any individual font; it is that
monospace fonts fall back to proportional fonts for missing characters,
instead of falling back to another monospace font with the desired

Bug description:
  The character "▷" (Unicode code point U+25B7, "white right-pointing
  triangle") takes up more space than other characters.  It extends
  outside of its bounding box such that it overlaps with the character
  immediately to its right.

  Please see the attached screen shot for an example of the triangle
  overlapping with the character 'M'.

  This triangle character is not the only one that is drawn too wide.
  U+25B6 is (somewhat trivially) another example. An even better example
  is the drachma sign, U+20AF, which overlaps the character that follows
