[Bug preprocessor/41067] Inconsistency in warnings on invalid \-escapes

Fri Aug 14 12:41:00 GMT 2009

------- Comment #1 from jsm28 at gcc dot gnu dot org  2009-08-14 12:41 -------
This applies to both C and C++; the code in question is in libcpp.

Strictly, for C++ the compiler should act as if 'Ã©' was replaced by
a UCN in phase 1 and so treat the second escape sequence like a valid
sequence \\u00E9 or one of the equivalent variants.  This is unlikely
to be what the user wanted so it should probably be accompanied by a
warning while accepting the code.  (This is in any case a separate
issue from the present bug report.)
