+Summary: width of non-latin1 text is measured incorrectly when printed from ANY Evo component - this breaks layout horribly
+
+Currently Ximian ships a very old version of gnome-print (0.25), that contains
+A LOT of cirtical i18n-related bugs. gnome-print-0.29 with most of the bugs
+fixed is available since May.. Not shipping gnome-print-0.29 is a biggest
+mistery of Ximian GNOME to me (add to that the fact that the main developer
+of gnome print is hired by Ximian)!!!
+
+ One of the most serious i18n problems of gnome-print is that
+    gnome_font_get_width_string
+and
+    gnome_font_get_width_string_n
+used EVEREYWHERE in Evo and gtkhtml to measure string width treat their
+argument as string iso-8859-1 encoding. This means that it measures width of
+non-latin1 strings incorrectly, leading to completely broken look of tables
+(e.g. mail headers are printed in table), right-aligned and centered text
+when printed!
+
+ In gnome-print above 0.25 there were introduced functions to measure a
+width of a string in utf8, named
+    gnome_font_get_width_utf8
+and
+    gnome_font_get_width_utf8_sized
+with same prototypes.
+  See last lines of
+    http://cvs.gnome.org/lxr/source/gnome-print/libgnomeprint/gnome-font.h
+for Lauris' comments on them.
+
+ Please use these functions instead of gnome_font_get_width_string{,_n} to fix
+severe problem of measuring width of non-latin1 strings.
+ And of course please include the latest version of gnome-print in XG.
+
+PS: of course there is a way to use low-level gnome-print-0.25 functions to
+measure string width in arbitrary encodings, see how I did it for
+Gnumeric in src/print-cell.c:get_width_string_n(). But including a latest
+gnome-print in XG is much better solution..
+
+PS: I posted it also to gnome-hackers ximian com,
