This is a really cool challenge, as flex only supports single byte
character sets (if not only ASCII). Their are some really weird approaches
throughout the web. Maybe I will take a look at it. Until, I changed the
spec to match the code ;-)

I updated the docs; thank you for the advice. The original approach of
using UTF-32 internally by default was driven by performance issues.
Handling UTF-32 is simpler than handling UTF-8. The current approach is
faster with UTF-8, which seems to be the better way...
