g++16 still does not support the use of non-ASCII characters in module-name, such as: ‘export module 汉字’ Is this how the module standard is defined, or is it just not implemented? I made some changes from libcody->buffer.cc myself, and it supports exporting ‘汉字’ now, but there are still other bugs. If gcc will support non-ASCII characters in the future, I won’t continue to do these things.
