If you're typing a file path, it's #

If you're typing a URL, it's %23.

The kfile dialogs allow you to type both. But a file path and a URL can be 
easily told apart.

The same goes for spaces vs %20, question marks vs %3f and the percent 
sign itself against %25. To make matters worse, there's also the issue of 
the encoding of non-ASCII letters. So, unless you really have to, you 
want to type file paths, not URLs.

If this breaks anywhere, there are wrong assumptions being made. The most 
common cause in KDE 3 is by far the use of the KURL constructor instead 
of KURL::fromPathOrUrl. We have fortunately fixed that for KDE 4 (the 
constructor does the expected thing). The next cause is probably the 
concatenation of file paths with "file://" to construct a URL (I argued 
this in kde-commits this week).

That means bug.
