error opening a file

[turbox]

i have this code

if ProcessExists("uTorrent.exe") Then
ProcessClose("uTorrent.exe")
Else
EndIf
$fo = fileopen(@AppDataDir & "\utorrent\settings.txt", 32)
if $fo = -1 Then exit
$fr = FileRead($fo)
ClipPut($fr)

but i get the half file characters

when i seve the file as unicode it read it well

what i can do to avoid the unicode convertion (it can't be automatic)?
