Questions and comments about Exercise Sheet 9 below this line (most recent on top)
I have a question concerning exercises 2-4: Is there any restriction saying that something indicates the length of a single UTF-8 sequence inside my large, random sequence? From how I read the description of the exercise, it seems as if it was valid to simply change each and every byte (when necessary) to be a 1-byte sequence. This way I have to change very few bits and end up with n UTF-8 sequences for ascii characters. However, this seems to be quite stupid and really easy. Maybe i missed / misread something.
