For dealing with ASCII we have strlen, strcat etc..
For UTF16(i.e, UCS2) we have wcscat and wcslen functions.
For dealing with UTF8 and UCS4 what are the functions available in C?
Assume Linux/gcc
I don’t think standard C libraries have UTF-8 functions. There are surely libraries for it.
However, normal str functions can be used with UTF-8 in many cases.
strlenworks well, returning the number of bytes (not characters).strcatworks (it also overruns your buffer easily, but this is normal for strcat).The reason is that the 0 character can’t appear in multi-byte UTF-8 data. So if it appears in a UTF-8 string, it’s surely its end, just like in ASCII.
