Subject: File name encoding confusion when renaming

I'm using a UTF-8 locale, and want my files to have UTF-8 filenames,
but some of them have Latin-1 names.  For the purpose of bug
reproduction, such a file can be created with:

echo foo > $(printf '\345')

That is, the file's name is "å" in Latin-1.

I want to rename this file to the same name in UTF-8:

M-: (rename-file "\345" "å")

This fails with:

Debugger entered--Lisp error: (file-already-exists "File already exists" 
"/tmp/Ã¥")
  rename-file("Ã¥" "\x8e5")
  eval((rename-file "Ã¥" "\x8e5"))
  eval-expression((rename-file "Ã¥" "\x8e5") nil)
  call-interactively(eval-expression)

However, if I set the OK-IF-ALREADY-EXISTS argument to t, renaming
succeeds:

M-: (rename-file "\345" "å" t)

Also, renaming the file to anything else succeeds.


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/local/share/emacs/22.0.93/etc/DEBUG for instructions.
