# Post-installation
Packages installed via Guix will not use the locale data of the host system.
Instead, you must first install one of the locale packages available
with Guix and then define the GUIX_LOCPATH environment variable:

```
guix install glibc-locales
export GUIX_LOCPATH=$HOME/.guix-profile/lib/locale
```

It is good to install font stuff

```
guix install fontconfig
fc-cache -rv
```

As an example, install a chinese font

```
guix install font-adobe-source-han-sans:cn
xset +fp $(dirname $(readlink -f ~/.guix-profile/share/fonts/opentype/fonts.dir))
```

maybe for other fonts like truetye fonts, you have to use another path like

```
xset +fp $(dirname $(readlink -f ~/.guix-profile/share/fonts/truetype/fonts.dir))
```
