edit2:
I succeeded in something, it is ineffecient, but working at least for now
In case someone needed it (Not sure if it would work on all unicode characters)
Spoiler
PHP Code:
stock ReverseString( input[ ], output[ ] ) { //new i, j; //for( i = strlen( input ) - 1, j = 0 ; i >= 0 ; i--, j++ ) //{ //output[ j ] = input[ i ]; //}
//output[ j ] = '^0';
new szUnicodeChar[] = "ï";
new iLen = strlen(input); new j = iLen - 1; new i;
