GCC 16 / libstdc++ implements the C++20 deletion of
std::operator<<(std::ostream&, wchar_t). NCtext.cc and NCRichText.cc stream
a wchar_t directly into a narrow std::ostream for debug output:
NCtext.cc:348:34: error: use of deleted function
'std::basic_ostream<char, _Traits>& std::operator<<(...wchar_t)'
Add a patch casting both sites to char (the values are ASCII).
