Code #1

Credit goes to @yushi2000 for providing the solve!

Observations

Analysing the code, we see that the i is repeated frequently without too many other characters in between.

Spoiler

Since we have something that looks like a splitter, lets analyse a bit more.
We have a to f and then i, counting the characters from a to i, we get 9.
This can fit in nicely with Morse were we can have . to .... and - to ---- and <space>
