wcscat() Function in Arduino

arduino_new:
use strcat()

char wcs[80] = "";

strcat(wcs, "these");

strcat(wcs, " wide strings ");

Thanks, but I need to use Unicode characters (Arabic Character) that are two bytes, also have to use wchar_t to save letters.

DON'T post screen shots of your code! Post the code!

But why not use strcat()?

I'm sorry, corrected.
