So I am working on the course to make my first font and really enjoying it. But I had an idea to create a jokey alternate set for the font based on the Standard Galactic Alphabet from Commander Keen. What would be the best way to do this? Would it be making it as a stylistic set?
What do you mean by “jokey alternate set”? If they’re just alternates of default letters, then a stylistic set would make sense.
When I mean “jokey” I mean they a cipher that really has no use for anything other than making something that has to be deciphered (or if you wanted to make some Commander Keen or Minecraft fanart). So wasn’t sure if a stylistic set was appropriate or if there was something better suited.
If there is a “mapping” of scrambled glyphs to plain glyphs, a stylistic set is a good solution. There is ne “encryption” OpenType feature 
Thank you all, I will just make a stylistic set then
