            Bug ID: 58708
           Summary: string literal operator templates broken
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: mustrumr97 at gmail dot com

The character type should be unqualified (char32_t instead of const char32_t).
Wide character types are broken.

U"

Obviously bugzilla doesn't like unicode.

U"\x10000\x10001\x10002"
current: <const char32_t, 0x00, 0x00, 0x01, 0x00, 0x01, 0x00, 0x01, 0x00, 0x02,
0x00, 0x01, 0x00>

expected: <char32_t, 0x10000, 0x10001, 0x10002>

Hristo,
Thanks for finishing your thought.

So if i have:

template<typename CharT, CharT... str>
  void
  operator""_foo
  {
    ChatT arr[]{str...};
  }

U"\x10000\x10001\x10002"_foo;

I should see this right?

#include <iostream>
template<typename CharT, CharT... str>
void operator""_foo(){
   CharT arr[]{str...};
   for(CharT i:arr) std::cout<<(int)i<<' ';
}
int main(){
   U"\x10000\x10001\x10002"_foo;
}

Current output: "0 0 1 0 1 0 1 0 2 0 1 0 0 0 0 "
Expected output: "65536 65537 65538 "
Without the \0, char32_t's instead of bytes.

The author of the paper intended CharT to be unqualified.
