Message-ID: <E18oAwF-0000Zr-00@fencepost.gnu.org> (raw)
In-Reply-To: <200302260749.QAA29494@etlken.m17n.org> (message from Kenichi Handa on Wed, 26 Feb 2003 16:49:15 +0900 (JST))
What a character in a unibyte buffer represents depends on a
context. It may be a character represented by a single
byte, or a raw byte not yet decoded, or a byte constituing a
multibyte form of the different character.
On the other hand, a character in a unibyte string always
represents a raw byte. Emacs coerces it into a character
represented by that single byte when a unibyte string is
concatenated with a multibyte string, or it is inserted in a
multibyte buffer.
------------------------------------------------------------
But, I'm not sure such a change is really necessary. Are
you sure that the change doesn't break the current usage of
unibyte strings?
To me this seems like a limitation, not an improvement. If you cut a
string out of a unibyte buffer, its contents have the same kind of
meaning as the unibyte buffers's contents.
Practically speaking, to implement this would seem to mean
removing features, but which features?
Meanwhile, I wonder whether there is any difference between
handing unibyte text inserted from a unibyte string
and unibyte text inserted from a unibyte buffer with
insert-buffer-substring. I would expect and hope they
work the same.
