I noticed that putclip/getclip have another problem.

These utils assume the charset is always UTF-8, however, cygwin
supports locales which charset is not UTF-8 (such as CP932, EUC-JP,
CP850, CP1251, etc.).

Therefore, what abount using mbstowcs/wcstombs rather than
MultiByteToWideChar/WideCharToMultiByte like the patch attached?
