Hello,
you should read the error descriptions:
compiler-error-c3872
compiler-error-c3873
compiler-error-c2017
I think, identifiers etc are written with Japanese signs/characters which the English compiler cannot handle.
Regards, Guido
Edit: show us some code with the error thrown. But I think you cannot use the English compiler because of Japanese characters. Multibyte and UTF-8 belong to strings, not to identifier names etc.
