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. A few years ago I found a bug in an input form of our web app, and I thoroughly enjoyed writing unit tests to verify the fix, including the 'poo' emoji. This was in Scala, BTW.
