Musl
Alpine Linux uses musl as its C standard library.
Locale
To Fix unicode defaults:
sed -i 's/#unicode="NO"/#unicode="NO"\nunicode="YES"/' /etc/rc.conf
Musl does not implement most of the locale features that glibc implements. The musl-locales package provides translations with varying degrees of completion. The below command installs a limited set of locales (languages) for musl (C library) generated console messages.
# apk add musl-locales
The musl-locales package also provides locale command. To list defined locales:
locale -a
This package includes a file in {[Path|/etc/profile.d/00locale.sh}}. You'll need to re-login or source it manually for locales to work.
Copy the default locale settings file /etc/profile.d/20locale.sh to a custom override file:
# cp /etc/profile.d/20locale.sh /etc/profile.d/20locale.sh.sh
Now custom override file can be edited with nano /etc/profile.d/locale.sh.sh.
Language support
To pull in the translation packages for all installed packages:
# apk add lang
To list available hunspell dictionary packages, so that you relevant language dictionary can be added:
apk list hunspell*
To list translation packages for your specific(xy) language:
apk list *-xy *-xy-*
For example, to list translation packages for Portuguese(pt) language:
apk list *-pt *-pt-*
