This looks good to me.  I think that the locale encoding should also be
a customization variable, but in the documentation it would be stated that
"You should not need to explicitly set this variable."  It is possible
to pass it simply as a key (in lower case) as is done for 'values'.  But
I think that the less variables like that there is, the best it is.  And
it could even make sense for a user to override the locale encoding if
the system is not well set up.  Maybe simply LOCALE_ENCODING?
