Ah, sorry, my fault. Attached now.

Ok, so wwwoflle is not the cause.

I can reproduce this output (except the question as I didn't unset
$TERM) with

env -uLANG lynx "http://radioscanningtw.jidanni.org/index.php?title=特殊:分類&uselang=en"

But that looks a little bit expected: If no UTF-8 is available, Lynx
tries to find replacements and "~@" looks like a good replacement for
some only indirectly visible character.

I also get it with

env -uLANGUAGE LC_MESSAGES=C LC_COLLATE=C LANG=zh_TW.UTF-8 LC_CTYPE=zh_TW.UTF-8 lynx "http://radioscanningtw.jidanni.org/index.php?title=特殊:分類&uselang=en"

But I guess this is because I have no zh_TW.UTF-8 locales installed.
So I tried it with this:

env -uLANGUAGE LC_MESSAGES=C LC_COLLATE=C LANG=en_GB.UTF-8 LC_CTYPE=en_GB.UTF-8 lynx "http://radioscanningtw.jidanni.org/index.php?title=特殊:分類&uselang=en"

That way I get again what's on my screenshot -- no U+200F visible.

Basically I can switch between those two representations (screenshot
and the "~@~O" view) by switching between LC_CTYPE=C and
LC_CTYPE=C.UTF-8. Unfortunately I was never able to reproduce what's
on your screenshot -- and I'm currently out of ideas what else could
have caused this. I also found no differences between
TERM=xterm-256color (what I have) and TERM=xterm.

What $TERM do you have set?

		Regards, Axel
