Re: Creating a unique path separator

If i have a tree structure, where the names can have ANY character in
them, what would be the best method for finding a 'unique series of
characters' to use as a separator when writing a path to an XML file?

For instance, the structure could look like this:

!"?$%^&*()_+1234567890-
    QWERTYUIOP{}qwertyuiop[]
        ASDFGHJKL:@~asdfghjkl;'#
            |ZXCVBNM<>?\zxcvbnm,./`?

then im stuck for using a single character (lets pretend that all the
extended characters have been used aswell - it could happen ... and
probably will when i least want it to), so i have to use two characters
for the separator. But of course, all the two character combinations
could have been used up aswell in a gargantuan super path! So i would
need to use three (or more - getting more and more unlikely, i know).
