Subject: [PATCH] Don't run regression tests in SQL_ASCII encoding by default
Instead, run them in the encoding that the locale selects, which is
more representative of real use.
Also document how locale and encoding for regression test runs can be
selected.

+ <para>
+ By default, the tests against a temporary installation use the
+ locale defined in the current environment and the corresponding
+ database encoding as determined by <command>initdb</command>. It
+ can be useful to test different locales by setting the appropriate
+ environment variables, for example:
+<screen>
+gmake check LANG=C
+gmake check LC_COLLATE=en_US.utf8 LC_CTYPE=fr_CA.utf8
+</screen>
+ For implementation reasons, setting <envar>LC_ALL</envar> does not
+ work for this purpose; all the other locale-related environment
+ variables do work.
+ </para>
+
+ <para>
+ When testing against an existing installation, the locale is
+ determined by the existing database cluster and cannot be set
+ separately for the test run.
+ </para>
+
+ <para>
+ You can also choose the database encoding explicitly by setting
+ the variable <envar>MULTIBYTE</envar>, for example:
+<screen>
+gmake check LANG=C MULTIBYTE=EUC_JP
+</screen>
+ Setting the database encoding this way typically only makes sense
+ if the locale is C; otherwise the encoding is chosen automatically
+ from the locale, and specifying an encoding that does not match
+ the locale will result in an error.
+ </para>
+
+ <para>
+ The encoding can be set for tests against a temporary or an
+ existing installation.
