Make wxUIActionSimulator::Text() to work with punctuation characters.

Currently this only really works when using the standard US keyboard layout as
we don't have information about the mapping from the characters to the keyboard
keys for the other layouts, which is not ideal but better than nothing as it
allows e.g. Text("foo_bar") to really produce "foo_bar" in the currently
focused text control instead of "foo-bar" as before.
