Tried latest source from HG and with solr also apart from lucene which I
tested previously. The problem with single quotes in HTML is still
there.
The revision:
http://hg.dovecot.org/dovecot-2.2/rev/ad028a950248
should have solved it but the relevant code no longer exists in
src/plugins/fts/fts-parser-html.c. Seems like it has been moved into
lib-mail. The file src/lib-mail/mail-html2text.c does contain something
about single quotes but to no avail. Can someone at-least confirm
existence of this issue?
