Hello,
I tried this with Sid version, Brandens preview packages and Daniels
development tree. In all cases, I noticed a significantly high
(gigantic) CPU usage when applications tried to load the Unicode
equivalents of their fonts. For example, Icewm and XChat1.9 need 5..15
seconds (depending on the theme) to start. Once they started, they work
fine. And normaly, with an latin locale, they start about 10 times
faster. So could anyone enlighten me about what is going on?
Example from the strace log:
open("/usr/X11R6/lib/X11/locale/locale.dir", O_RDONLY) = 6
fstat64(6, {st_mode=S_IFREG|0644, st_size=28105, ...}) = 0

Etc... And:
# grep iso10646 log | wc -l
1526
Too many lookups, IMHO. Same with latin1 locale:
grep 8859 log2 | wc -l
114
Gruss/Regards,
Eduard.
