[issue14937] IDLE's deficiency in the completion of file names (Python 32, Windows XP)

[Roger Serwy]

Roger Serwy <roger.serwy at gmail.com> added the comment:

I agree that chr(32) should be included in FILENAME_CHARS. 

The algorithm for backward searching checks that each character is contained in FILENAME_CHARS. I'm concerned about running time, as expanding FILENAME_CHARS to include all valid Unicode would be a large set to search. Do you know a better algorithm for determining when to perform a file-system completion when in a string?

Also, are there any Unicode code points above 127 that are not valid in a filename? I appreciate that different file systems can have different constraints but I don't know all these subtle points.
