Every version of Mercurial can read repos _created_ by any older
version.. and will complain otherwise. So if 'hg status' works, you're
golden. I recently discovered that the repo hosting hg itself was
created circa 0.7.. and has obviously worked without trouble since that
time. See here for more details:

Linux is -way way way- more permissive about filenames.

Except in .hg/hgrc, there shouldn't be any. It's quite common to
move/share repos between Linux and Windows.

Mercurial internally treats all files as binary; it treats a .txt the
same as a .jpg. Only commands that display diffs or the like make any
attempt to detect if a file is text... so they won't put too much
garbage on your screen.
