Multi-byte (<acronym>MB</acronym>) support is intended to allow
|
||||||
|
<productname>Postgres</productname> to handle
|
||||||
|
multiple-byte character sets such as EUC (Extended Unix Code), Unicode and
|
||||||
|
Mule internal code. With <acronym>MB</acronym> enabled you can use multi-byte
|
||||||
|
character sets in regular expressions (regexp), LIKE, and some
|
||||||
|
other functions. The default
|
||||||
|
encoding system is selected while initializing your
|
||||||
|
<productname>Postgres</productname> installation using
|
||||||
|
<application>initdb</application>. Note that this can be
|
||||||
|
overridden when you create a database using
|
||||||
|
<application>createdb</application> or by using the SQL command
|
||||||
|
CREATE DATABASE. So you can have multiple databases each with
|
||||||
|
a different encoding system.

<para>
|

<acronym>MB</acronym> also fixes some problems concerning 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.)

Here is an example of configuring

<productname>Postgres</productname> to use a Japanese encoding by
|

|
default:
|

|
|
||||||
|
<programlisting>
|

|
% ./configure --enable-multibyte=EUC_JP
|
||||||
|
</programlisting>
|
||||||
|
</para>
|
||||||
|
|
||||||
|
<para>
|
||||||
|
If the encoding system is omitted (./configure --enable-multibyte),
|
||||||
|
SQL_ASCII is assumed.

<title>Setting the Encoding</title>
|

|
|
||||||
|
<para>
|
||||||
|
<application>initdb</application> defines the default encoding
|
||||||
|
for a <productname>Postgres</productname> installation. For example:
|
||||||
|
|
||||||
|
<programlisting>
|
||||||
|
% initdb -E EUC_JP
|
||||||
|
</programlisting>
|
||||||
|
|
||||||
|
sets the default encoding to EUC_JP(Extended Unix Code for Japanese).
|
||||||
|
Note that you can use "--encoding" instead of "-E" if you prefer
|
||||||
|
to type longer option strings.
|
||||||
|
If no -E or --encoding option is given, the encoding
|
||||||
|
specified at the compile time is used.
|
||||||
|
</para>
|
||||||
|
|
||||||
|
<para>
|
||||||
|
You can create a database with a different encoding:
|
||||||
|
|
||||||
|
<programlisting>
|
||||||
|
% createdb -E EUC_KR korean
|
||||||
|
</programlisting>
|
||||||
|
|
||||||
|
will create a database named "korean" with EUC_KR encoding. The
|
||||||
|
another way to accomplish this is to use a SQL command:
|
||||||
|
|
||||||
|
<programlisting>
|
||||||
|
CREATE DATABASE korean WITH ENCODING = 'EUC_KR';
|
||||||
|
</programlisting>
|
||||||
|
|
||||||
|
The encoding for a database is represented as an
|
||||||
|
<firstterm>encoding column</firstterm> in the
|
||||||
|
<literal>pg_database</literal> system catalog.
|
||||||
|
You can see that by using -l or \l of psql
|
||||||
|
command.
|
||||||
|
|
||||||
|
<programlisting>
|
||||||
|
$ psql -l

To enable the automatic encoding translation, you have to tell
|
||||||
|
<productname>Postgres</productname> the encoding you would like
|
||||||
|
to use in frontend. There are
|
||||||
|
several ways to accomplish this.

||||||
|
<command>\encoding</command> allows you to change frontend
|
||||||
|
encoding on the fly. For
|
||||||
|
example, to change the encoding to SJIS, type:
|
||||||
|
|
||||||
|
<programlisting>
|
||||||
|
\encoding SJIS
|
||||||

</programlisting>
|

Using libpq functions.
|

|
<command>\encoding</command> actually calls
|

PQsetClientEncoding() for its purpose.
|
||||||
|
|
||||||
|
<programlisting>
|
||||||
|
int PQsetClientEncoding(PGconn *<replaceable>conn</replaceable>, const char *<replaceable>encoding</replaceable>)
|
||||||
|
</programlisting>
|
||||||
|
|
||||||
|
where <replaceable>conn</replaceable> is a connection to the backend,
|
||||||
|
and <replaceable>encoding</replaceable> is an encoding you
|
||||||
|
want to use. If it successfully sets the encoding, it returns 0,
|
||||||
|
otherwise -1. The current encoding for this connection can be shown by
|
||||||
|
using:
|
||||||
|
|
||||||
|
<programlisting>
|
||||||
|
int PQclientEncoding(const PGconn *<replaceable>conn</replaceable>)
|
||||||
|
</programlisting>
|
||||||
|
|
||||||
|
Note that it returns the "encoding id," not the encoding symbol string
|
||||||
|
such as "EUC_JP." To convert an encoding id to an encoding symbol, you
|
||||||
|
can use:
|

|
|
||||||
|
<programlisting>
|
||||||
|
char *pg_encoding_to_char(int <replaceable>encoding_id</replaceable>)
|

<programlisting>

SET CLIENT_ENCODING TO 'encoding';
|

</programlisting>
|

Also you can use SQL92 syntax "SET NAMES" for this purpose:

<programlisting>
|

SET NAMES 'encoding';
|

|
<programlisting>
|
||||||
|
SHOW CLIENT_ENCODING;
|
||||||
|
</programlisting>
|
||||||
|
|

To return to the default encoding:
|

RESET CLIENT_ENCODING;

Suppose you choose EUC_JP for the backend, LATIN1 for the frontend,
|
||||||
|
then some Japanese characters could not be translated into LATIN1. In
|
||||||
|
this case, a letter cannot be represented in the LATIN1 character set,
|
||||||
|
would be transformed as:
