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.
|
|
|
|
The patch also fixes some problems concerning with 8-bit single byte
|
|
character sets including ISO8859. (I would not say all of problems
|
|
have been fixed. I just confirmed that the regression test ran fine
|
|
and a few French characters could be used with the patch. Please let
|
|
me know if you find any problem while using 8-bit characters)
|
|
|
|
How to use
|
|
|
|
After applying the MB patch, create src/Makefile.custom with a line
|
|
including:
|
|
|
|
MB=encoding_system
|
|
|
|
where encoding_system is one of:
|
|
|
|
EUC_JP Japanese EUC
|
|
EUC_CN Chinese EUC
|
|
EUC_KR Korean EUC
|
|
EUC_TW Taiwan EUC
|
|
UNICODE Unicode(UTF-8)
|
|
MULE_INTERNAL Mule internal
|
|
|
|
Example:
|
|
|
|
% cat Makefile.custom
|
|
MB=EUC_JP
|
|
|
|
If MB is not defined, nothing is changed except better supporting for
|
|
8-bit single byte character sets.
