            Bug ID: 65545
           Summary: Demangling of char template parameters always produces
                    integer value
           Product: gcc
           Version: 4.9.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gcc at cohi dot at

Given a template class declared with a "char" template parameters, for example

   template< char ... C > struct one;

and demangling the class name of an instance like

   one< 'a' >

with the abi::__cxa_demangle() function then the demangled result is

   one<(char)97>

which is much harder to read...

It would be great if this could be fixed to print 'c' whenever isprint() is
true for the value of c.

Thanks!
