To specify an alternative encoding, provide an `encoding` argument. ```javascript var buf = string2buffer( '7468697320697320612074c3a97374', 'hex' ); // returns <Buffer> ``` The following `encodings` are supported: - `utf8` (`utf-8`) - `hex` - `binary` - `ascii` - `ucs2` - `base64` </section> <!-- /.usage --> <!-- Package usage notes.
