+It is important that the locale found using the heuristic above is tested prior

+<para>The above commands should print the country and language names, the
+character encoding used by the locale, the local currency and the prefix to
dial
+before the telephone number in order to get into the country. If any of the
+commands above fail with a message similar to the one shown below, this means
+that your locale was either not installed in Chapter 6 or is not supported by
+the default installation of Glibc.</para>

+<para><computeroutput>locale: Cannot set LC_* to default locale: No such file
or directory</computeroutput></para>
+
+<para>If this happens, you should either install the desired locale using the
<command>localedef</command> command, or consider choosing a different locale.
+Further instructions assume that there are no such error messages from Glibc.
+</para>
+
+<para>Some packages beyond LFS may also lack support for your chosen locale.
One
+example is the X library (part of the X Window System), which outputs the
+following error message:</para>
+
+<para><computeroutput>Warning: locale not supported by Xlib, locale set to
C</computeroutput></para>
+
+<para>Sometimes it is possible to fix this by removing the charmap part of the
+locale specification, as long as that does not change the character map that
+Glibc associates with the locale (this can be checked by running the
+<command>locale charmap</command> command in both locales). For example, one
+would have to change "[EMAIL PROTECTED]" to
+"[EMAIL PROTECTED]" in order to get this locale recognized by
Xlib.</para>
+
+<para>Other packages can also function incorrectly (but may not necessarily
+display any error messages) if the locale name does not meet their
expectations.
+In those cases, investigating how other Linux distributions support your locale
+might provide some useful information.</para>
