Title:
  ltsp-localapps can not open files with accents in URI

Status in ltsp package in Ubuntu:
  New

Bug description:
  If I try to open a file in a localapp, and the filename (or path)
  contains accented letters, the URI is not passed correctly to that
  local app.

  For example if I run:
  ltsp-localapps vlc /home/user/testé/video.mov

  Then on the client, in syslog, i see:
  ltsp-localappsd: Executing command as username user: vlc "/home/user/test303251/video.mov"

  And vlc gives an error saying that this URI is not valid.


  The problem seems to be located in the way this filename is passed:
  # xprop is used to set the X property LTSP_COMMAND:
  xprop -root -f LTSP_COMMAND 8s -set LTSP_COMMAND "/usr/bin/vlc --started-from-file %U"

  which is read by the daemon /usr/bin/ltsp-localappsd

  # Poll for LTSP_COMMAND changes and execute
  xprop -notype -root -spy LTSP_COMMAND | while read junk_x junk_y LTSP_COMMAND ; do
    # Strip off leading and trailing double-quotes.
      LTSP_COMMAND=${LTSP_COMMAND%\"}
      LTSP_COMMAND=${LTSP_COMMAND#\"}
