Hi, here are the patches to enhance existing MB handling. This time
I have implemented a framework of encoding translation between the backend and the frontend. Also I have added a new variable setting command: SET CLIENT_ENCODING TO 'encoding'; Other features include: Latin1 support more 8 bit cleaness See doc/README.mb for more details. Note that the pacthes are against May 30 snapshot. Tatsuo Ishii

2. PGCLIENTENCODING
|
||||
|
||||
If an environment variable PGCLIENTENCODING is defined on the
|
||||
frontend, automatic encoding translation is done by the backend. For
|
||||
example, if the backend has been compiled with MB=EUC_JP and
|
||||
PGCLIENTENCODING=SJIS(Shift JIS: yet another Japanese encoding
|
||||
system), then any SJIS strings coming from the frontend would be
|
||||
translated to EUC_JP before going into the parser. Outputs from the
|
||||
backend would be translated to SJIS of course.
|
||||
|
||||
Supported encodings for PGCLIENTENCODING are:
|
||||
|
||||
EUC_JP Japanese EUC
|
||||
SJIS Yet another Japanese encoding
|
||||
EUC_CN Chinese EUC
|
||||
EUC_KR Korean EUC
|
||||
EUC_TW Taiwan EUC
|
||||
MULE_INTERNAL Mule internal
|
||||
LATIN1 ISO 8859-1 English and some European laguages
|
||||
|
||||
Note that UNICODE is not supported(yet). Also note that the
|
||||
translation is not always possible. Suppose you choose EUC_JP for the
|
||||
backend, LATIN1 for the frotend, then some Japanese characters cannot
|
||||
be translated into latin. In this case, a letter cannot be represented
|
||||
in the Latin character set, would be transformed as:
|
||||
|
||||
(HEXA DECIMAL)
|
||||
|
||||
3. SET CLIENT_ENCODING TO command
|
||||
|
||||
Actually setting the frontend side encoding information is done by a
|
||||
new command:
|
||||
|
||||
SET CLIENT_ENCODING TO 'encoding';
|
||||
|
||||
where encoding is one of the encodings those can be set to
|
||||
PGCLIENTENCODING. To query the current the frontend encoding:
|
||||
|
||||
SHOW CLIENT_ENCODING;
|
||||
|
||||
To return to the default encoding:
|
||||
|
||||
RESET CLIENT_ENCODING;
|
||||
|
||||
This would reset the frontend encoding to same as the backend
|
||||
encoding, thus no endoing translation would be performed.

||||
