*Why* that file name exists is clear -- someone was trying to type a file
name into a box. He typed ".ooo", and then decided he didn't like that, so
he typed ^H three times, which moved the cursor back three spaces, then he
typed "test", which wrote over the offending "ooo", but didn't actually
remove them from the program's input buffer. Similarly, the final ^H was to
correct the second "f" so he could replace it with "i". The name he thought
he was getting was ".testfile".

But you've identified the Subversion problem correctly -- a file name can
contain "non-printable" characters, which are forbidden in XML. Worse, what
you might think is a valid escape sequence to represent it -- &8; -- is also
forbidden in XML, because "character entities" are forbidden from
representing non-printable characters. See the discussion in


Subversion may need to extend XML to allow this (and has to verify that its
XML parser can deal with it).
