iTeleport supports non-US keyboard layouts with a few configuration settings:

• Windows users:  Uninstall your VNC server and install UltraVNC since it supports international keyboards natively.  You will not need to make any further changes.

• Mac users:  There are two ways to enable International keyboard support:
  • The best way is to use the modified Vine-Jaadu Server and to set Vine's Preferences > Device > Keyboard Layout to Current Layout.  You should use the same keyboard layout on the Mac as on the iPhone (e.g. French, German, etc.), and it will output the correct character to your VNC screen.
    • To use special characters like ê, ë, é, and è, you have to set your Mac keyboard to Unicode Hex Input.
      
      
  • Instead, if you don't want to install Vine, and prefer to use the built-in Leopard Screen Sharing or Tiger Apple Remote Desktop, you will need to switch your Mac keyboard layout to US English to be able to use international keyboards in iTeleport.  Once you do so, you will be able to use special characters without any other configuration changes.
