Comment 4 for bug 50213

Ah, that's interesting. With the dash, i.e. charset=iso-8859-15 it works fine viewed directly (file://) but using Apache to serve it, only the middle one works.

But actually it is not correct for Konqueror to have the file links with _two_ slashes, but it expects three slashes just like Firefox (at least version 3.5.5 does). And if you use three slashes (i.e. file:///müller), you have the exactly same behaviour in Konqeror as in Firefox:

view local file: all three links work
view it through Apache: only the middle one works.

So you seem to be right, that it is the Apache header which somehow messes it up.
So this doesn't seem to be a Konqueror bug, if a bug at all. Can you confirm, Daniel?
