Answer:
Yes, almost certainly someone does. But you will be more likely to find 
them on a Rails mailing list. This is the mailing list for Ruby, the 
programming language.

If you install ruby 1.9 somewhere, it has some features you can use to 
experiment with encodings. For example:

$ irb19 --simple-prompt
>> str = "Caf辿"
=> "Caf辿"
>> str.bytes.map { |x| "%02x" % x }
=> ["43", "61", "66", "c3", "a9"]
>> str.encode!("ISO-8859-1")
=> "Caf
>> str.bytes.map { |x| "%02x" % x }
=> ["43", "61", "66", "e9"]
>> 

But I suggest you keep your 1.8.6 for production use.
