There's no such thing as "UTF-8 characters". UTF-8 is an encoding of Unicode character set. If you want to know whether language compilers and interpreters accept UTF-8 encoded characters, then you will need to consult the documentation of the relevant compiler. AFAIK, C/C++ compilers support this only in recent versions. For Emacs Lisp, the answer is YES, as the default encoding of ELisp files is UTF-8.
