I'm sorry, but the previous patches are insufficient to handle non-ASCII file 
names.
The menu "Recent Files" in "File" in the menu-bar does not display such 
names correctly.
In addition, when updating the "Recent Files" menu, UnicodeDecodeError 
raises in _implicit_ conversion of unicode filename given by tkFileDialog to 
ASCII string.

So I made a new patch.  Do not use the previous patches, please.
The new patch converts every multi-byte file name into unicode early in 
IOBinding; thus the file path is correctly displayed in the title bar.  
And it converts every unicode name into multi-byte string explicitly when 
updating the menu.
Note that IDLE writes the recent file names as a text file.  Conversion into 
string is necessary anyway.
