Hi,

Since I have updated my Rails gems to 2.2.2, when I create a new entry  
in DB which has a permalink I get the following error message:  
uninitialized constant ActiveSupport::Multibyte::Handlers

Do you know if permalink\_fu is compatible with Rails 2.2.2? Is there an  
option I have forgotten to pass to make it work correctly?

Permalink is not compatible do to the changes in  
ActiveSupport::Multibyte.

Change line 11 in permalink\_fu.rb from  
`# s =
ActiveSupport::Multibyte::Handlers::UTF8Handler.normalize(str.to_s, :kd)
`

to

` s = str.mb_chars.downcase.strip.normalize(:kd) `
