ARGF.internal_encoding â encoding
Instance Public methods
Returns the internal encoding for strings read from ARGF
as an
Encoding
object.
If ARGF.set_encoding
has been called with two encoding names,
the second is returned. Otherwise, if
Encoding.default_external
has been set, that value is
returned. Failing that, if a default external encoding was specified on the
command-line, that value is used. If the encoding is unknown, nil is
returned.
