Instance Method Details

#parse_bytes_into_sequences(bytes) ⇒ Object

Parses a collection of bytes into key code sequences. All multi-byte sequences (e.g. [27, 91, 67]) will be left alone where-as all other byte sequences will be converted to UTF-8.

E.g.

parse_bytes_into_sequences [97, 98, [27, 91, 67], 99, 198, 146]
# => ["a", "b", [27, 91, 67], "c", "ƒ"]
