Yes, that is the safest bet. The LANG sets a default, but the
LC_COLLATE, LC_TIME, LC_NUMERIC and LC_MONETARY should better
be set to "C" to overrule the LANG in their domains.

Leave the LC_ALL undefined or empty, as this one overrules
every other locale setting (unless you really want everything
to be set to "C").
