testcase

The attached testcase doesn't seem to be parsed correctly by clang:

  ~$ g++ widechar.cc -o widechar
  ~$ ./widechar
  194
  ~$ llvm/Debug+Asserts/bin/clang++ widechar.cc -o widechar
  widechar.cc:4:15: warning: extraneous characters in wide character constant
        ignored
    wchar_t c = L'Â';
                ^
  1 warning generated.
  ~$ ./widechar
  -126

The two-byte character literal is 0xc3 0x82.
