1 5.9 Character Set
1 =================
1 
1 Sticking to the ASCII character set (plain text, 7-bit characters) is
1 preferred in GNU source code comments, text documents, and other
1 contexts, unless there is good reason to do something else because of
1 the application domain.  For example, if source code deals with the
1 French Revolutionary calendar, it is OK if its literal strings contain
1 accented characters in month names like "Flore'al".  Also, it is OK (but
1 not required) to use non-ASCII characters to represent proper names of
1 contributors in change logs (⇒Change Logs).

1    If you need to use non-ASCII characters, you should normally stick
1 with one encoding, certainly within a single file.  UTF-8 is likely to
1 be the best choice.
