If you have some time on your hands, you could try benchmarking it against
Python 3.1's (py3k) decoder. There are two cases to consider:
- mostly non-ASCII input, such as the "utf-8 demo" file mentioned in the page 
- mostly ASCII input, such as will happen very often (think HTML, XML, log
files, etc.)

The py3k utf-8 decoder is optimized for the latter.
