PHP код:

    new sFind[][] = {"ą", "ć"};
    new sReplace[][] = {"a", "c"};
    new sSubject[500] = "Asią byla ćasna.";
    printf("Old string: %s", sSubject);
    for(new i = 0; i < sizeof(sFind); i++)
    {
        sSubject = str_replace(sFind[i], sReplace[i], sSubject);
    }
    printf("New string: %s", sSubject); 


Here you go, as you wanted it. Obviously play around with the size of the `sSubject` string.

To add any other replacements, simply add it to the arrays.
