CAUTION1: Note that before 7.2 LATIN5 meant ISO 8859-5 mistakely. In 7.2
LATIN5 measn ISO 8859-9. If you have LATIN5 database created on
7.1 or before and want to migrate to 7.2, you should be very
carefull about this change.

CAUTION2: Not all API supports encodings listed above. For example,
PostgreSQL JDBC driver does not support MULE_INTERNAL, LATIN6,
LATIN8 and LATIN10.

<para>
An automatic encoding translation between Unicode and other
encodings has been supported since PostgreSQL 7.1.
Because this requires huge conversion tables, it's not enabled by default.
For 7.1 it's not enabled by default.
To enable this feature, run configure with the
<option>--enable-unicode-conversion</option> option. Note that this requires
the <option>--enable-multibyte</option> option also.
</para>
<para>
For 7.2, <option>--enable-unicode-conversion</option> is not necessary.
The unicode conversion functionality is automatically enabled
if <option>--enable-multibyte</option> is specified.
