From: t-ishii@sra.co.jp
Hi, here are patches I promised (against 6.3.2):
* character_length(), position(), substring() are now aware of
multi-byte characters
* add octet_length()
* add --with-mb option to configure
* new regression tests for EUC_KR
(contributed by "Soonmyung. Hong" <hong@lunaris.hanmesoft.co.kr>)
* add some test cases to the EUC_JP regression test
* fix problem in regress/regress.sh in case of System V
* fix toupper(), tolower() to handle 8bit chars
note that:
o patches for both configure.in and configure are
included. maybe the one for configure is not necessary.
o pg_proc.h was modified to add octet_length(). I used OIDs
(1374-1379) for that. Please let me know if these numbers are not
appropriate.

Introduction

|

MB patch is intended for allowing PostgreSQL to handle multi-byte

charachter sets such as EUC(Extende Unix Code), Unicode and Mule
|

internal code. With the MB patch you can use multi-byte character sets
|

in regexp and LIKE. The encoding system chosen is determined at the

compile time.
