So, here's a paper I found very nice to get started into this subject: http://swtch.com/~rsc/regexp/regexp1.html If anyone's interested into becoming our PostgreSQL regexp hero and still needs a good kicker, I would recommend starting here :) I see this paper mention the regexp code from Plan9, which supports both UTF8 and other muti-byte encodings, and is released as a library under the MIT licence: http://swtch.com/plan9port/unix/ Regards, -- Dimitri Fontaine http://2ndQuadrant.fr PostgreSQL : Expertise, Formation et Support -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
