Ok, now I've definately encountered some non-obvious behaviour.
A symlink target of 100 bytes or less keeps the same name, while
a target of more than 100 bytes gets munged from the converstion
to UTF-8 and back.

For example, the symlink created by the following script doesn't
change the link target:

fname=$(printf $(jot -b \\303\\240 -s '' 50))
ln -fs $fname test
tar -cf - test | tar -tvf -

but if the 50 in the jot command is changed to 51, the target
changes.  So I guess that the link target doesn't fit in the
standard header anymore, and needs an extended tag.  Having
different behaviour for the two cases does seem odd.
