Yes, that bit is self-evident but when are eight bit strings needed?
I do not understand that question. Characters over 127 are used in
Emacs strings to represent non-ASCII characters.
Mathieu Lacage stated on gdb-patches:
....a lot of people (the first
which comes to my mind is libxml2) decided to use "unsigned char *" to
identify utf-8 encoded strings in C.
That is likely too in other programs. Emacs has its own internal
coding and does not use utf-8.
