Mangling not right for wchar/dchar.

Comment #1 by turkeyman — 2018-06-09T21:11:35Z

wchar_t needs a typedef. It's just an alias, and can't identify it to mangle properly. wchar and dchar should be char16_t, char32_t. DMD doesn't have any C++11 support... so the unit-tests for DMD need special-case handling.

Separate issue creates for wchar_t: https://issues.dlang.org/show_bug.cgi?id=18997 PR for this issue here: https://github.com/dlang/dmd/pull/8342 Problem is unit-tests that link against DMC++ fail, because DMC doesn't support utf16/32 char types.

Actually, it looks like DMC++ *does* support char16_t/char32_t: https://www.digitalmars.com/ctg/CPP0x-Language-Implementation.html Just need to jig the unit-tests to make sure that's invoked somehow?
