Hi,
Under Slitaz 4, I just edited /etc/profile so that it exports all variables sourced from locale.conf:
line 38 is changed from
export LANG LC_ALL
to
export LANG ${!LC_@}
This allows fine-tuning of locale, such as
LC_CTYPE=fr_FR.UTF-8
LC_NUMERIC=C
LC_COLLATE=C
for example.
I hope you'll find this patch worth applying.
