8594 - [PP]Unix: add support for -iso10646-1 fonts

Status: VERIFIED FIXED

(Core :: Layout, defect, P3)

Description

[Erik van der Poel]

There are several X fonts the end with "-iso10646-1", and we probably should
support them. They don't contain a fixed set of glyphs like the other X fonts
(such as -iso8859-1). The glyph set can be determined by looking at the per_char
array in XFontStruct. If that is not there, we should look for a font property
called _XFREE86_GLYPH_RANGES. This was invented by Mark Leisher and I.

Comment 1

[Erik van der Poel]

Basic -iso10646-1 support was added a while ago, but the _XFREE86_GLYPH_RANGES
support is still missing. Marking M14 (after beta).

Comment 2

[Erik van der Poel]

There was an email discussion with Markus Kuhn and Mark Leisher, and we
determined that _XFREE86_GLYPH_RANGES is not necessary, since the per_char
array is always there, except for abnormal fonts such as those that have 0
in the average width field of the XLFD font name. Mozilla already "filters"
those out (to support scalables). So this bug can now be closed, since we
already added the per_char array support a while ago.

Based on erik's comments, marking verified fixed in the Nov 29th build.
