/* TODO: This function is currently called through the RIF, and in
some cases font_type is UNKNOWN_FONT. We currently allow the
cached metrics to be used, which seems to work, but in cases
where font_type is UNKNOWN_FONT, we probably haven't encoded
char2b appropriately. All callers need checking to see what they
are passing. This is most likely to affect variable width fonts
outside the Latin-1 range, particularly in languages like Thai
that rely on rbearing and lbearing to provide composition. I
don't think that is working currently anyway, but we don't seem
to have anyone testing such languages on Windows. */
