how to use this?

[inspire22]

I'm having problems with 1.9.2 having strings it "thinks" are encoded as utf-8, but then when I try a regex against them i throws an ArgumentError: invalid byte sequence in UTF-8.

I assume this module could help me force_encoding it into the right encoding, so I can then encode! it properly into utf-8? Sounds like a lot of work.

Sounds like I'll need to run this on every string submitted to my web applications as well, so hopefully it's not slow?

Thanks!
