Re: Charset conversion error

It seems not.

$ cat koi8.sh
printf "SELECT '==\xb9=='"|PGCLIENTENCODING=WIN1251 psql -p 5435 koi8

$ psql -p 5435 -c 'select version()' koi8
version
---------------------------------------------------------------------------------------------------------
PostgreSQL 8.1.3 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.3.2 20031218 (Vine Linux 3.3.2-0vl8)
(1 row)

$ sh koi8.sh
?column?
----------
== ==
(1 row)

As you can see PostgreSQL 8.1.3 converts 0xb9 in Windows-1251 to a
space of KOI8.
