I mainly wonder how the text in the buffer is really represented.  Is it
like a string (which is utf8-ish), but with a gap somewhere?

Thanks; that's a helpful node.  However, the node seems to, er, not
match up to how functions really are written.  The code is full of BEGV,
PT and CHECK_STRING, which is likely somewhat mysterious to new
hackers.  At least I was confused.  :-)
