+@quotation NOTE
+@cindex @env{LANGUAGE} environment variable
+As described in @ref{Locales}, environment variables with the same
+name as the locale categories (@env{LC_CTYPE}, @env{LC_ALL}, etc.)
+influence @command{gawk}'s behavior (and that of other utilities).
+
+Normally, these variables also affect how the @code{gettext} library
+finds translations.  However, the @env{LANGUAGE} environment variable
+overrides the @env{LC_@var{xxx}} variables. Many GNU/Linux systems
+may define this variable without your knowledge, causing @command{gawk}
+to not find the correct translations.  If this happens to you,
+look to see if @env{LANGUAGE} is defined, and if so, use the shell's
+@command{unset} command to remove it.
+@end quotation
+
+For testing translations of @command{gawk} itself, you can set
+the @env{GAWK_LOCALE_DIR} environment variable. See the documentation
+for the C @code{bindtextdomain()} function and also see
+@ref{Other Environment Variables}.
