Subject: From: "Denis V. Dmitrienko" <denis@null.net>

What it does:
It solves stupid problem with cyrillic charsets IP-based on-fly recoding.
take a look at /data/charset.conf for details.
You can use any tables for any charset.
Tables are from Russian Apache project.
Tables in this patch contains also Ukrainian characters.

Then run ./configure --enable-recode
