Your argument that people may want to use 'grep' in ISO-8859-1 encoded text
files is convincing. I'm applying this patch, to support non-UTF-8 locales
on MacOS X:


2009-01-24  Bruno Haible  <address@hidden>

        Add support for non-UTF-8 locales on MacOS X.
        * lib/config.charset: Add CP1131, ARMSCII-8, PT154 to the list of
        canonical encodings. For Darwin 7 and newer, don't map traditional
        encodings to UTF-8.
        Reported by Vincent Lefevre <address@hidden>
        at <http://savannah.gnu.org/bugs/?25235>.
