For most of the lines, it is just their normal lines, just using shift cypher IE first 8 letters byte value get shifted forward by 1, next 8 by 8. Of course, this means letters that are high up on the alphabet go outside it into symbols and capital letters have different results than lower case. Because of the simple cypher, it's relatively easy to reverse engineer with a few example lines. Even if you didn't know about text encoding, you could create your own table to translate any line in the game. Some lines are handcrafted though, like all of nyalice's of course. But one of these crafted lines stands out in particular. If you are at low sen when you first meet holmes, when he normally tells you to run towards him he says something completely different.
