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).
