Huh.  Someone should warn Apple then, since $LANG has been set to en_US.UTF-8 by default in OS X for years now.  I just checked, and sed/grep/vi/ed/etc all still work. :)

It’s a good idea to change it.  We have outgrown ISO-Latin1, and UTF-8 solves a host of ugly I18N interoperability problems when used consistently.
