Check KeySymbol before return null in TryCreateRawKeyEventArgs to prevent skipping cultural character.
What does the pull request do?
This PR makes sure we don't skip a special cultural character when it's typed using custom cultural tools.
What is the current behavior?
Any special cultural character will be deleted upon typing into Textbox, all keyDown or keyUp events will receive a blank character instead of the special character.
What is the updated/expected behavior with this PR?
Special cultural character should be typed and inserted normally in TextBox.
How was the solution implemented (if it's not obvious)?
