Invalid byte sequence in UTF-8 when requesting a page

I get an "invalid byte sequence in UTF-8" on page requests (permalinks), and I have no idea why I cannot play it, but I have many exceptions like:

A ArgumentError occurred in products#index:

 invalid byte sequence in UTF-8
 activesupport (3.0.4) lib/active_support/core_ext/object/blank.rb:68:in `=~'

-------------------------------
Request:
-------------------------------

 * URL       : http://www.mysite.com/category/category-name-\x8E~ice
 * Parameters: {"page"=>1, "controller"=>"products", "action"=>"index", "category"=>"category-name-\x8E~ice"}

The line at the end should not be there ("- \ x8E ~ ice"). Any idea why this shows up or what I can do to debug / reproduce it?

thank

we created rails middleware that filters out all the weird encodings that cannot be processed in our application.

Like @phoet, I also used Rails middleware to solve similar encoding problems.

Tested on Ruby 1.9.3 (no Iconv):

If you use apache (and mod_rails), you can prevent these invalid URL requests from uninstalling the Rails application completely by running this answer:
