# StringIO.set_encoding (from ruby core) --- strio.set_encoding(ext_enc, [int_enc[, opt]]) => strio --- Specify the encoding of the StringIO as *ext_enc*. Use the default external encoding if *ext_enc* is nil. 2nd argument *int_enc* and optional hash *opt* argument are ignored; they are for API compatibility to IO.
