Great, this is one of the things I mentioned at the helpneeded page. I
just had a look at your code and I really like it. One question I'm
not sure about: I noticed the use of some strlen calls there. Are they
used in a UTF-8 safe way there or would it be possible that they split a
multibyte char? If that could happen we should add a check to strip
invalid UTF-8 chars from beginning and end of the snippet - this would
be a nice addition to the utf-8 lib.
BTW: I didn't see any differences in the snippets generated by opt1 and
opt2. Do you have any ideas in which directions we should look to see if
there are problems?
