@user2277550 you always need to escape the escape character if it occurs within the data; you can construct escaping schemes any way you want, but if you don’t do that you get ambiguity in at least one of multiple ways; the only other option is to use a different encoding scheme (something like base128 or so) that changes all characters, or to use an escape char that cannot be present in input data (like \xFF in UTF-8), but you have to check that.
