I agree, I have also missed a block comment.

I don't see what this has to do with Erlang. What is shown is up to the
operating system. Erlang does make some assumptions on what is visible
characters and what is control character, and the compiler does some
assumptions about upper and lower case letters. If Latin 1 and Latin 9
only matters in one character, it shouldn't be any concern for Erlang.
