for input/output handles. For example, if both input and out are
chosen to be C<:utf8>, a C<:std> will mean that STDIN, STDOUT, and
STDERR are also in C<:utf8>. On the other hand, if only output is
-chosen to be in C<:encoding(koi8r)', a C<:std> will cause only the
+chosen to be in C<< :encoding(koi8r) >>, a C<:std> will cause only the
STDOUT and STDERR to be in C<koi8r>. The C<:locale> subpragma
implicitly turns on C<:std>.
