I've tested these commands and got the same output as you did.
I also tested with utf-8 characters from my own locale:
$ echo 'foo åäö bar' | write user
$ echo 'foo åäö bar' | wall
For the wall case the message appeared as expected:
Broadcast message from user@machine (pts/2) (Sun Nov 6 09:05:56 2016):
foo åäö bar
But the write message appeared as:
Message from user@machine on pts/2 at 09:05 ...
foo M-CM-%M-CM-$M-CM-6 bar
EOF
My conclusions are:
- wall is working as intended. The reason you sometimes
see backslash-escaped ascii codes is that your locale (on the
receiving side) does not consider those characters as "printable
characters".
- write is likely not working properly with utf-8 characters.
The problem in write is likely caused in the "write_line" function
which writes the output byte-by-byte via fputc(_careful) which
then breaks multi-byte characters.
