I don't experience that with emacs -Q on:

GNU Emacs 22.3.1 (i386-apple-darwin8.11.1, Carbon Version 1.6.0)

What does `C-h C RET' in the *Async Shell Command Output* show?  Mine
says:

Coding system for saving this buffer:
  Not set locally, use the default.
Default coding system (for new files):
  1 -- iso-latin-1 (alias: iso-8859-1 latin-1)

Coding system for keyboard input:
  nil
Coding system for terminal output:
  1 -- iso-8859-1 (alias of iso-latin-1)

Defaults for subprocess I/O:
  decoding: 1 -- iso-latin-1 (alias: iso-8859-1 latin-1)

  encoding: 1 -- iso-latin-1 (alias: iso-8859-1 latin-1)


Priority order for recognizing coding systems when reading files:
  1. iso-latin-1 (alias: iso-8859-1 latin-1)
  2. mule-utf-8 (alias: utf-8)
  3. mule-utf-16be-with-signature (alias: utf-16be-with-signature 
mule-utf-16-be utf-16-be)
  4. mule-utf-16le-with-signature (alias: utf-16le-with-signature 
mule-utf-16-le utf-16-le)
  5. iso-2022-jp (alias: junet)
  6. iso-2022-7bit
  7. iso-2022-7bit-lock (alias: iso-2022-int-1)
  8. iso-2022-8bit-ss2
  9. emacs-mule
  10. raw-text
  11. japanese-shift-jis (alias: shift_jis sjis cp932)
  12. chinese-big5 (alias: big5 cn-big5 cp950)
  13. no-conversion

  Other coding systems cannot be distinguished automatically
  from these, and therefore cannot be recognized automatically
  with the present coding system priorities.

  The following are decoded correctly but recognized as iso-2022-7bit-lock:
    iso-2022-7bit-ss2 iso-2022-7bit-lock-ss2 iso-2022-cn iso-2022-cn-ext
    iso-2022-jp-2 iso-2022-kr
