I find specially nice the completion feature for filenames of IDLE when they include long paths, something that is more mand more frequent with big disks and infinite amounts of files.

But there is a small problem with it. If the name of any of the directories that intervene in the path to the file has any special character in it (meaning by that I suppose any non ASCII character), the completion mechanism ceases to work.

For instance, if the path were:

    d:/Biblioteca/Técnica/informática/Python ...

the cesation of the help would occur after the incorporation of *Técnica*, because its *e* is accented.

There is plenty of cheap software which shows this minor deficiency, but I consider that IDLE for Python 3 should not be in that group.
