From 687366b920caa5de6ea0b66b70cf2a11e5399f7b Mon Sep 17 00:00:00 2001 From: Sebastian Spaeth Date: Mon, 11 Jul 2011 15:02:12 +0200 Subject: [PATCH] python: represent message tags as unicode instances Rather than returning simply strings and having to guess their encoding, return explicit unicode() strings for the tags. Xapian stores UTF8, so we know that they come as UTF8 encoded string. Note: I tried to directly use the c_wchar_p type of the ctypes library which translates directly into an unicode type, but that did not work out so well, so we take c_char_p and .decode() them manually.
