[babel-devel] octets-to-string with UTF8 and Byte Order Marker

[Rob Blackwell]

Luis,

I updated my .emacs as follows and it worked

(set-language-environment "UTF-8")
(load (expand-file-name "~/quicklisp/slime-helper.el"))
(setq slime-net-coding-system 'utf-8-unix)

I'm still a little confused as to why the length is 4 and not 3 - shouldn’t the byte order mark have been discarded?

Many thanks!

Rob.

Hello again,

I've tried this out and it works for me:

  CL-USER> (babel:octets-to-string (babel-tests::ub8v 239 187 191 102 111 111))
  "foo"
  CL-USER> (length *)
  4

I'm guessing you're using SLIME and you haven't set your slime-net-coding-system to 'utf-8-unix or something similar. Have a look at the *inferior-lisp* when your Lisp crashes to see if that's the case.

HTH,
