The system's locale is _always_ UTF-8.

We are mis-communicating: there are no non-UTF-8 locales under Android,
which is a guarantee from the Android developers.  There are different
languages, but they are uniformly encoded as UTF-8.

There is _NO_ system locale besides UTF-8.  Irrespective of the language
selected, the locale installed amounts to en_US.utf-8, with the
intention being that such programs as spell checkers will detect and
apply the user's language preferences themselves.

How can it be fixed, when there are only two locales (C and UTF-8) in
existence?  Android spell checkers are meant to provide their own means
for detecting and applying the system's language preferences, because
the system does not on their behalf.

Thanks.
