[sup-devel] Encoding of message snippet in xapian

Hi 

While debuging the trackeback posted below I discovered that my xapian
index contains some of the message snippets in ASCII-8BIT and others
in UTF-8. This leads to probelems when building the thread-view for
collapsed messages for messages wich have non 7-bit ASCII characters
in their snippet. message_patina_lines combines the snippet which
comes from the xapian index and is (sometimes) in ASCII-8BIT with
other parts of the message which are in UTF-8.

I don't know exactly how I ended up with a xapian index which has some
strings in ASCII-8BIT and others in UTF-8. I guess it's because I
first used sup with Ruby 1.8 and only recently switched to Ruby 1.9.1.
What's the expected encoding of things coming from the xapian index?
Is there a way to fix the index? Or is a fix in sup needed for this?
Or should I just recreate my index from scratch?

Running sup with Ruby 1.8 avoids the problem. But I guess it only
masks it because 1.8 is not encoding aware.
