As noted in the libc++ 19 release notes [1], std::char_traits<> is now only provided for char, char8_t, char16_t, char32_t and wchar_t, and any instantiation for other types will fail. This causes x11-toolkits/mygui to fail to compile with clang 19 and libc++ 19, resulting in errors similar to: In file included from /wrkdirs/usr/ports/x11-toolkits/mygui/work/mygui-MyGUI3.4.2/MyGUIEngine/include/MyGUI_Common.h:12: /usr/include/c++/v1/string:820:42: error: implicit instantiation of undefined template 'std::char_traits<unsigned short>' 820 | static_assert(is_same<_CharT, typename traits_type::char_type>::value, y | ^ /wrkdirs/usr/ports/x11-toolkits/mygui/work/mygui-MyGUI3.4.2/MyGUIEngine/include/MyGUI_UString.h:213:4: note: in instantiation of template class 'std::basic_string<unsigned short>' requested here 213 | dstring::iterator mIter; | ^ /usr/include/c++/v1/__fwd/string.h:23:29: note: template is declared here 23 | struct _LIBCPP_TEMPLATE_VIS char_traits; | ^ These can be fixed by using `char16_t` instead of `uint16_t` for the `code_point` type, and `char32_t` instead of `uint32_t` for the `unicode_char` type.
