+
+Mar 22, 2000
+	* Add new libpq functions PQsetClientEncoding, PQclientEncoding
+	* ./configure --with-mb=EUC_JP
+	  now deprecated. use 
+	  ./configure --enable-multibyte=EUC_JP
+	  instead
+  	* Add SQL_ASCII regression test case

+
+Mar 23, 1999
+	* Add support for KOI8(KOI8-R), WIN(CP1251), ALT(CP866)
+	  (thanks Oleg Broytmann for testing)
+	* Fix problem with MB and locale
+
+Jan 26, 1999
+	* Add support for Big5 for fronend encoding
+	  (you need to create a database with EUC_TW to use Big5)
+	* Add regression test case for EUC_TW
+	  (contributed by Jonah Kuo <jonahkuo@mail.ttn.com.tw>)
+
+Dec 15, 1998
+	* Bugs related to SQL_ASCII support fixed
+
+Nov 5, 1998
+	* 6.4 release. In this version, pg_database has "encoding"
+	  column that represents the database encoding
+
+Jul 22, 1998
+	* determine encoding at initdb/createdb rather than compile time
+	* support for PGCLIENTENCODING when issuing COPY command
+	* support for SQL92 syntax "SET NAMES"
+	* support for LATIN2-5
+	* add UNICODE regression test case
+	* new test suite for MB
+	* clean up source files
+
+Jun 5, 1998
+	* add support for the encoding translation between the backend
+	  and the frontend
+	* new command SET CLIENT_ENCODING etc. added
+	* add support for LATIN1 character set
+	* enhance 8 bit cleaness
+
+April 21, 1998 some enhancements/fixes
+	* 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
+
+Mar 25, 1998 MB PL2 is incorporated into PostgreSQL 6.3.1
+
+Mar 10, 1998 PL2 released
+	* add regression test for EUC_JP, EUC_CN and MULE_INTERNAL
+	* add an English document (this file)
+	* fix problems concerning 8-bit single byte characters
+
+Mar 1, 1998 PL1 released

+Appendix:
+
+[Here is a good documentation explaining how to use WIN1250 on
+Windows/ODBC from Pavel Behal. Please note that Installation step 1)
+is not necceary in 6.5.1 -- Tatsuo]
+
+Version: 0.91 for PgSQL 6.5
+Author: Pavel Behal
+Revised by: Tatsuo Ishii

+Licence: The Same as PostgreSQL

+Sorry for my Eglish and C code, I'm not native :-)
+
+!!!!!!!!!!!!!!!!!!!!!!!!! NO WARRANTY !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
+
+Instalation:
+------------
+1) Change three affected files in source directories 
+    (I don't have time to create proper patch diffs, I don't know how)
+2) Compile with enabled locale and multibyte set to LATIN2
+3) Setup properly your instalation, do not forget to create locale
+   variables in your profile (environment). Ex. (may not be exactly true):
+	LC_ALL=cs_CZ.ISO8859-2
+	LC_COLLATE=cs_CZ.ISO8859-2
+	LC_CTYPE=cs_CZ.ISO8859-2
+	LC_MONETARY=cs_CZ.ISO8859-2
+	LC_NUMERIC=cs_CZ.ISO8859-2
+	LC_TIME=cs_CZ.ISO8859-2
+4) You have to start the postmaster with locales set!
+5) Try it with Czech language, it have to sort
+5) Install ODBC driver for PgSQL into your M$ Windows
+6) Setup properly your data source. Include this line in your ODBC
+   configuration dialog in field "Connect Settings:" :
+	SET CLIENT_ENCODING = 'WIN1250';
+7) Now try it again, but in Windows with ODBC.
+
+Description:
+------------
+- Depends on proper system locales, tested with RH6.0 and Slackware 3.6,
+  with cs_CZ.iso8859-2 loacle
+- Never try to set-up server multibyte database encoding to WIN1250,
+  always use LATIN2 instead. There is not WIN1250 locale in Unix
+- WIN1250 encoding is useable only for M$W ODBC clients. The characters are
+  on thy fly re-coded, to be displayed and stored back properly
+ 
+Important:
+----------
+- it reorders your sort order depending on your LC_... setting, so don't be
+  confused with regression tests, they don't use locale
+- "ch" is corectly sorted only in some newer locales (Ex. RH6.0)
+- you have to insert money as '162,50' (with comma in aphostrophes!)
+- not tested properly
