You can fix it simple by checking the inputtext before using it with this stock :

pawn Code:

stock CheckDialogBug(message[])
{
    new message_length = strlen(message);
    for(new i; i < message_length; i++)
    {
        if(message[i] == '%')
        {
            return 1;
        }
    }
    return 0;
}

Now you're gonna use this checking in all DIALOG_STYLE_INPUT dialogs.

Example of usage:

Code:

if(CheckDialogBug(inputtext)) return SendClientMessage(playerid, 0, "{FFFFFF}You can't use '%' in strings.");
