Input japanese character (and probably other double-byte characters) in TextEdit and get text with Qt::LineEdit.text(), and it would see '?'.

Sample Code
---
#!/usr/bin/ruby

require 'Qt'

class MyMainWindow < Qt::MainWindow
  slots 'slot_return_pressed()'

  def initialize
    super
    @line = Qt::LineEdit.new(self)
    connect(@line, SIGNAL("returnPressed()"),
            self, SLOT("slot_return_pressed()"))
  end

  def slot_return_pressed
    text = @line.text
    puts text ### Error! japanese character -> '?' 
  end
end

app = Qt::Application.new(ARGV)
main_window = MyMainWindow.new

app.mainWidget = main_window
main_window.show
app.exec
