| Doug Gwyn has now said

|   It was certainly the original intent of C99 that identifiers would match
|   only if encoded identically.  It would probably be wise for any importing
|   process to apply "canonicalization" to source code before it reaches the
|   compiler.
| 
| and Henry Spencer has said
| 
|   The approach I ended up using in a non-C project was to say that (a) all
|   occurrences of an identifier must be encoded identically, and (b) it is
|   forbidden for two different identifiers to have the same normalized form
|   (for a suitable definition of normalization).

  You said you resent your message to c++std-compat.  I don't believe
it ever appeared on that list.  Please, could you double-check?
