[Message part 3 (text/plain, inline)]

This change:

2009-03-05  Kenichi Handa  <handa <at> m17n.org>

	* font.c (font_select_entity): New function.
	(font_find_for_lface): Use font_select_entity to select a font.

	* fontset.c (fontset_find_font): If a font found without
	restricting of the characters C doen't support C, try to find a
	font with C restriction.

has broken display of tibetan characters.  The characters are no longer
found in the gnu-unicode font.  Instead a weird, one-pixel wide empty
box is shown for each font (see the attached snapshot).  I have also
attached the font logs from before and after that change.

Andreas.
