The problem is MultiByteToWideChar(CP_ACP) in PROFILE_Load() will return decomposed string with '0x003f' for some multibyte characters when LC_CTYPE is zh_CN.UTF-8 or ja_JP.UTF-8. Then PROFILE_Load() will cache an wrong string and return a wrong result for GetPrivateProfileStringA().

That is certainly wrong. Very first thing to do (as usual) is to add
a test case demonstarting the issue.
