Re: [sup-devel] sup 0.13



UTF-8 handles most cases but I still have to deal with emails in ISO2022-JP, Shift-JIS and EUC-JP. After some research it seems Xapian has no support for Asian languages. I will try to make some tests and open an issue if I cannot make it work.

I can see in the sup configuration file that the stem language can be configured but there are no CJK stemmers for Xapian that I can find.

Hi Horacio,

consider opening an issue at
https://github.com/sup-heliotrope/sup/issues to make sure this doesn't
disappear. Some changes will probably be made to the indexer when going
to Mail (from RMail), but I hope to be able to migrate the existing
index. Perhaps its time to get it right for arbitrary languages as well.
I am unfamiliar with Japanes/Chinese - does UTF-8 cover the needs?

Mail is better at handling UTF-8 and I think there was some fork that
had some extra support for Japanese.
