RFC2047 recommends use of ISO-8859-*

   When there is a possibility of using more than one character set to
   represent the text in an 'encoded-word', and in the absence of
   private agreements between sender and recipients of a message, it is
   recommended that members of the ISO-8859-* series be used in
   preference to other character sets.

As locale will not be created from XML in tests, so default_locale
should not depend on XML record in tests.
