Besides official Morse codes in ITU-R specification, there are also other (unofficial) ones. This version adds a support for them as this has been requested by many users. However, a cautious approach has been chosen because these codes need not to be well-known and some of them can even be ambiguous (the same code may represent multiple different letters). So the app tries to avoid them whenever possible to prevent misunderstanding. Moreover, the unofficial codes are excluded from learning.
