Ferret's LowerCaseFilter (which converts tokens and queries to lower
case) uses the C function towlower() [1] to convert multi-byte
characters (e.g. UTF-8 characters with accents) to lower case. Maybe
the Ferret code does not inherit the correct locale from environment.rb?
I'm not sure how to fix this, perhaps someone else does.
