Subject: bug#10919: emacs-mule/utf-8 difference
Date: Thu, 01 Mar 2012 16:39:57 +0100 [thread overview]
Message-ID: <4F4F984D.2000901@inria.fr> (raw)
Hi,
I have a problem regarding coding systems:
I'm using process-send-string to send substrings of a buffer through a
socket, after setting the process encoding and decoding systems to
emacs-mule.
I expect the number of bytes written to match the byte-length of the
substring as obtained by position-bytes, since the specification of
position-bytes in emacs-devel is to always work with the emacs-mule
encoding. From emacs-devel:
"The byte sequence of a buffer after decoded is always in emacs-mule (in
emacs-unicode-2 branch, it's utf-8). So, changing
buffer-file-coding-system or any other coding-system-related variables
doesn't affects position-bytes."
However, this is not the case with 3bytes utf8 characters:
position-bytes counts them as 3 bytes, but process-send-string wirtes 4
bytes.
Setting the process coding systems for the socket to utf-8 solves the
problem, but I don't think it will with other coding systems, even if I
used buffer-file-coding-system instead, since position-bytes does not
use it.
What is the real expected behavior of these things, and how to make this
correct ?
Regards,
Tiphaine Turpin
