In source code, the main issue is not whether another editor will
display it properly but whether the other tools that use the file will
handle it properly.

Usually this will depend on the programming language, where the
definition of the language usually clarifies which kinds of encodings
and/or charsets are allowed (and where, since the rule can be different
in different parts, such as inside comments or strings).

E.g. Emacs Lisp uses utf-8 (since Emacs-24.4) and supports the use of
basically any Unicode characters in source code, such as inside
identifiers.

[ BTW, "UTF characters" is kind of meaningless.  You'll want to learn to
  distinguish OT1H characters, and OTOH the encodings that can be used
  to represent them as sequences of bytes.  ]
