> I am having problems with the Solr HTML stripper.
> After some investigation, I have found the cause to be that the
> stripper is replacing the removed HTML with spaces. This obviously
> breaks when the HTML is in the middle of a word, like "G&uuml;nther".
> So, without knowing what I was doing, I hacked together a fix that
> uses offset correction instead.
> That seemed to work, except that closing tags and attributes still
> broke the positioning. With even less of a clue, I replaced read()
> with next() in the two methods handling those.
> Finally, invalid HTML also gave wrong offsets, and I fixed that by
> restoring numRead when rolling back the input stream.
> At this point I stopped trying to break it, so there may still be more
> problems. Or I might have introduced some problem on my own. Anyway, I
> have put the three patches at the bottom of this mail, in case
> somebody wants to move along with this issue.
