fix locale issue

[Vasilisc]

I found this solution
---
     export I18NPATH=$SNAP/usr/share/i18n
     export LOCPATH=$SNAP_USER_DATA
     export LC_ALL=$LANG
     LANG1=$(echo $LANG | cut -f1 -d.)
     ENC=UTF-8
     LOC="$LANG"
     # generate a locale so we get properly working charsets and graphics
     if [ ! -e $SNAP_USER_DATA/$LOC ]; then
       $SNAP/usr/bin/localedef --prefix=$SNAP_USER_DATA -f $ENC -i 
$LANG1 $SNAP_USER_DATA/$LOC
     fi
