Actually 335, 336, 337, 189 and to some extent 105 are the same issue/have the 
same reason. Microsoft states that dots and spaces at the end of a filename are 
removed (http://support.microsoft.com/kb/115827/en-us, 
http://msdn.microsoft.com/en-us/library/aa365247), but non-ascii characters are 
explicitly allowed. I also did not find any indication that + should not be 
allowed. At least urls like script.cgi+ and script.cgi%2B do not open 
script.cgi, so CGI code disclosure should not be an issue here.

Chinese version of the operating system, allowing the file name and directory 
name to use Chinese, Chinese (including CJK) using two bytes greater than 0x7f 
ASCII codes.

Exclude greater than 0x7f bytes, mongoose handle CJK coding the directory name 
to be wrong.
