[french speaking and layout is fr_BE] -- TextEdit object/widget issue

I use the widget declared like this:

```
let commentaires = elements.add(
TextEdit::multiline(&mut self.strComment).
desired_rows(12).
background_color(Color32::from_rgb(255,249,206)).
text_color(Color32::BROWN).
char_limit(MAX_COMMENT_SZ.into()));
if commentaires.gained_focus()
{
self.strComment = "".to_string();
}
```
I had the uncomfortable surprise to experience that the '^' (scancode 0x1a 0x9a) can not be used to display the characters like 'î' or 'û' or 'ê' for example in French we use lot of 'accents circonflexes' and I simply can't display them in TextEdit.
