You don't need an array for that. I guess you're just looking for numbers and alphabetic characters:

stock isValidPassword(const szPass[]) {
    for(new i = 0; szPass[i] != EOS; ++i) {
        switch(szPass[i]) {
            case '0'..'9', 'A'..'Z', 'a'..'z':
                continue;
            default:
                return 0;
        }
    }
    return 1;
}
