Test to test UTF-8
Sorry but UTF-8 is still broken. less-378+iso247-20030108.diff is the reason
why it is broken. Quite frankly, this is a patch that makes quite a few
assumptions on how multibyte scripts work and probably breaks other non CJK
centric multibyte encodings. There used to be a patch for less to support CJK.
The authors had given up the idea of supporting non ISO2022 scripts and thus
the compiled patched less was called jless so that it could coexist alongside
plain vanilla less, letting the user choose to use one or the other. If this is
the same patch or a derivatif of it that you are using I would advise you to
just drop it or create a jless package.
Try reading the attached file to convince you how much less is broken. It works
fine with the forementioned patch.
Another possible test: read a man page in an xterm. "man man" is a good example
less-378-7 is the real fix. Part of the patch was missing.
Fix confirmed in less-378-11.1.
