Available Encodings

Below is a table of encodings. Here, we track which encodings can be represented using the Lucky 7 technique, whether or not we have produced such an implementation, and (if applicable) a link to said implementation.

As a general point, we hope to support almost all of the encodings here in one form or another! If you’d like to request prioritization of a certain encoding, let us know.
