Guile says they are character strings. > You are saying they are both at once. Yes, to be viable in real-life situation, Guile needs to support character strings with occasional embedded raw bytes that cannot be interpreted as characters. Which means string implementation needs to have a special representation for these raw bytes that would allow lossless round-trip, and at the same time avoid the pitfalls some of which were mentioned here.
