Checking possible to extract string using UTF8

[PhoneixS]

When checking if strings can be extracted by xgettext it do it without --from-code option so it assume is ASCII.

Although string must be in English this don't mean that you can't have other non-ascii characters (for example in names) and I think is safer to call it assuming is encoded in UTF-8.

So this code:

check_xgettext_ok()
{
    if [ "$(which xgettext)" != "" ]
    then
        s_echo "Checking possible to extract string"

        if xgettext -L Shell "/tmp/script" &> /dev/null
        then
            s_ok 3
        else
            s_err 3
        fi
    fi
}

should be writted as:

check_xgettext_ok()
{
    if [ "$(which xgettext)" != "" ]
    then
        s_echo "Checking possible to extract string"

        if xgettext -L Shell --from-code=UTF-8 "/tmp/script" &> /dev/null
        then
            s_ok 3
        else
            s_err 3
        fi
    fi
}
