Yes.

Yes, but that is only in the case that you read a file into
a multibyte buffer by raw-text. This conversion from raw
byte sequence to multibyte form is what done by
string-to-multibyte which I wrote in the previous mail.
On process reading, if raw-text is used, the process output
is at first read as a unibyte string, the string is coverted
to multibyte by string-as-mulitbyte (not by not-yet-existing
string-to-multibyte), then inserted in a multibyte buffer.
I don't remember why the current code does as above. I
think the behaviour what Eli wrote is more consistent with
the behaviour of file reading.
Shall I change the code as what Eli wrote (by introducing
the new function string-to-multibyte)?
By the way, it may be clean to have all these functions in
parallel, and spare one section describing the difference of
MAKE, AS, TO conversions in info.
string-make-multibyte
string-as-multibyte
string-to-multibyte
string-make-unibyte
string-as-unibyte
string-to-unibyte (perpaps the same as string-as-unibyte, or
it should signal an error if non-ascii,
non-eight-bit-XXX is contained).
buffer-make-multibyte
buffer-as-multibyte (same as (set-buffer-multibyte BUFFER t))
buffer-to-multibyte
buffer-make-unibyte
buffer-as-unibyte (same as (set-buffer-multibyte BUFFER nil))
buffer-to-nuibyte
