It is likely the result of a cut-and-paste from a UTF-encoded page into links on the pages you see linking to you like this. You'll also often see strange links with commas and periods at the end of the URL due to auto-linked URLs in sentences written on forums and blogs -- The poorly-implemented auto-linkers include the sentence punctuation in the URL itaelf!

Please post your best-effort code as a basis for focused discussion.

Thanks,

I tried a simple redirect like:

Redirect 301 /%C2%A0 http://www.example.com/
(That of course didn't work)

I tried "" marks like you do with a URL with spaces/%20's in them.

Redirect 301 /"%C2%A0" http://www.example.com/

I also tried a number of different RewriteRules.

RewriteCond %{REQUEST_URI} !\/^%C2%A0\$ [NC]
RewriteRule ^%C2%A0$ http://www.example.com/ [R=301,L]

These are some of my examples. I am completely off aren't I?

[edit reason] example.com [/edit]

Try this instead:

RewriteCond %{THE_REQUEST} ^[A-Z]+\ /[^%?\ ]*\%
RewriteRule ^. http://www.example.com/ [R=301,L]

Here, we examine the original (possibly-encoded) client request instead of the un-encoded REQUEST_URI
