I've done a few hours (!!) of digging just to find where the / is
replaced by a ⁄ and couldn't find it within the dolphin sources.
Actually, the new file stuff all seems to be going through
DolphinNewFileMenu which goos back to a KNewFileMenu which can be
found here: http://api.kde.org/4.9-api/kdelibs-apidocs/kfile/html/knewfilemenu_8cpp_source.html

actually used.

Adding David to the CC since he might know more here? (he is in the
author list of that file). David, what i'm trying to figure out is why
a "/" is replaced by a "⁄" (notice the subtle difference) when it's
used inside a filename. A "\" doesn't get replaced and just works as
expected.
