at the string escape table of chapter 2 it appears that Unicode
characters can be either 16-bit or 32-bit. That must be a lot of
potential characters! It will be interesting to look up the full
Unicode tables. Quickly scanning the comparing strings section, I
wonder if I should have been so quick to jump in with a couple of
responses to the other thread going on recently!
I don't see a mention of byte strings mentioned in the index of my
text. Are these just the ASCII character set?
Since I have not made it formally into this chapter yet, I don't
really have specific questions, but I would be interested in anything
