ContainInvalidCharacters
I created this function on any time ago... Good to check and create "normal" passwords and to set player name.

Check if have invalid characters in one string.

pawn Код:

#define function%0(%1) stock %0(%1)

function ContainInvalidCharacters(string[])
{
    // Add more if you need/want. (if you add new characters, you should add the quantity of characters that you put to the variable. ("19"))
    new InvalidCharacters[19][] =
    {
        "&","$","^","?","_",".","*","#","(",")",
        "[","]","{","}","=","+","-","!","@"     
    };
    
    for(new checkloop; checkloop<sizeof(InvalidCharacters); checkloop++)
    {
        if(strfind(string, InvalidCharacters[checkloop]) != -1) return true;
    }
    
    return false;
}

An example :

pawn Код:

public OnGameModeInit()
{
    new varstring[15] = "mystringwith@";
    if(ContainInvalidCharacters(varstring)) return print("- 'varstring' contains invalid characters !");
    
    return 1;
}

Output :
