            Bug ID: 103902
           Summary: Only the addition space between string-literal and
                    identifier in a literal-operator-id will be accepted
                    by GCC where the identifier is not in a basic
                    character set
           Product: gcc
           Version: 11.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: xmh970252187 at gmail dot com
  Target Milestone: ---

bool operator ""_Ã(unsigned long long){
   return true;
}

The above code is not accepted by GCC. It should be passed around by adding a
space between "" and _Ã. However, it is accepted by Clang, and it is not
necessary to add that space.
