uniq -c chokes on international characters

[blue0ne]

To whom it may concern,
    After executing a uniq on a list of names, some of which contain
accent characters, I noticed that the lines with acccent characters were
not being consolidated into a non-repeating pattern.  For instance, the
following is sampling of the output of a command line which counts the
unquie posters to the nessus-devel list and their corresponding number
of posts.

      1 Luca Andreucci
      1 Maciej Soltysiak
      1 Marc Spitzer
      1 Mark Curphey
      1 Martin Ma?ok
      1 Martin Ma?ok
      1 Martin Ma?ok
      1 Martin Ma?ok
      1 Martin Ma?ok
      1 Martin Ma?ok
      1 address@hidden
      1 Matt Petteys


Below is yet another sampling, which made me realize the issue:

      1 Guillaume Valadon
