ChangeLog problems

[Luc Teirlinck]

Since the latest changelog entry for the synching with Tramp, I got
problems with the ChangeLog.  I am not sure what to do about them:

These default coding systems were tried to encode text
in the buffer `ChangeLog<lisp>':
  iso-2022-7bit-unix iso-latin-1
However, each of them encountered these problematic characters:
  iso-2022-7bit-unix:           
  iso-latin-1:            
The first problematic character is at point in the displayed buffer,
and C-u C-x = will give information about it.

Select one of the following safe coding systems, or edit the buffer:
  utf-8 utf-16 utf-16 utf-16 utf-16be utf-16le
Or specify any other coding system
at the risk of losing the problematic characters.
