For a French keyboard mapping, using a slightly modified
version of the program.

------------------------8<-------------------------
KeyDown: KeyCode: D1, Modifiers: None
KeyPress: &
KeyUp: KeyCode: D1, Modifiers: None

KeyDown: KeyCode: D2, Modifiers: None
KeyPress: é
KeyUp: KeyCode: D2, Modifiers: None

KeyDown: KeyCode: D0, Modifiers: None
KeyPress: à
KeyUp: KeyCode: D0, Modifiers: None

KeyDown: KeyCode: D7, Modifiers: None
KeyPress: è
KeyUp: KeyCode: D7, Modifiers: None

KeyDown: KeyCode: D9, Modifiers: None
KeyPress: ç
KeyUp: KeyCode: D9, Modifiers: None

KeyDown: KeyCode: ShiftKey, Modifiers: Shift
KeyDown: KeyCode: OemCloseBrackets, Modifiers: Shift
KeyUp: KeyCode: OemCloseBrackets, Modifiers: Shift

KeyUp: KeyCode: ShiftKey, Modifiers: None

KeyDown: KeyCode: E, Modifiers: None
KeyPress: ë
KeyUp: KeyCode: E, Modifiers: None
------------------------8<-------------------------

This could make things interesting because accented
characters are generated differently depending
on the country code of the keyboard layout.
For example:

http://www.246.ne.jp/~joe/info/latin1.htm

Note that in the above output, this sequence:

------------------------8<-------------------------
KeyDown: KeyCode: ShiftKey, Modifiers: Shift
KeyDown: KeyCode: OemCloseBrackets, Modifiers: Shift
KeyUp: KeyCode: OemCloseBrackets, Modifiers: Shift

KeyUp: KeyCode: ShiftKey, Modifiers: None

KeyDown: KeyCode: E, Modifiers: None
KeyPress: ë
KeyUp: KeyCode: E, Modifiers: None
------------------------8<-------------------------

is the two-key sequence used to generated "ë" on
a French (FR) keyboard.

Let's look at the output of ö for both French (FR):

------------------------8<-------------------------
KeyDown: KeyCode: ShiftKey, Modifiers: Shift
KeyDown: KeyCode: OemCloseBrackets, Modifiers: Shift
KeyUp: KeyCode: OemCloseBrackets, Modifiers: Shift

KeyUp: KeyCode: ShiftKey, Modifiers: None

KeyDown: KeyCode: O, Modifiers: None
KeyPress: ö
KeyUp: KeyCode: O, Modifiers: None
------------------------8<-------------------------

and German (DE) keyboard layouts:

------------------------8<-------------------------
KeyDown: KeyCode: Oemtilde, Modifiers: None
KeyPress: ö
KeyUp: KeyCode: Oemtilde, Modifiers: None
------------------------8<-------------------------

So it looks like you need to factor the locale in
when generating these if you want to do it in a
compatible way.

Let me know if you want me to follow up on this more.
I'm feeling less lazy now and need this for my
TextBox keyboard support.
