How to encrypt using Mary Stuart cipher?
The encryption imagined by Mary Stuart uses a correspondence between letters (but also words) and symbols. The complete alphabet is regularly changed but kept secret between her and its correspondents.
Example: an alphabet found is visible in the UK National Archives 
The best known of the alphabets is the one used during the Babington plot, led by Sir Anthony Babington, which aimed to kill Queen Elizabeth I so that Mary Queen of Scots could take the throne. An intercepted message used this alphabet (these are the characters that are the most common on the Internet):

The alphabet contains 5 blank characters that can be used as space or word separator (this makes the frequency analysis more complex).
