124 and so on.) So we really should be querying the face for the desired

125 font, rather than the character for the charset, and that's what would

126 determine the separation into runs.

127 - The widechar versions of fontconfig (and therefore Xft) functions
|
|

128 seem to be just bigendian Unicode. So there's actually no need to use
|
|
|
129 the 8-bit versions in computing runs and runes, it would seem.
