   // Even though we create a flipped HWND for a native button when the locale
   // is right-to-left, Windows does not render text for the button using a
   // right-to-left context (perhaps because the parent HWND is not flipped).
   // The result is that RTL strings containing punctuation marks are not
   // displayed properly. For example, the string "...ABC" (where A, B and C are
   // Hebrew characters) is displayed as "ABC..." which is incorrect.
   //
   // In order to overcome this problem, we mark the localized Hebrew strings as
   // RTL strings explicitly (using the appropriate Unicode formatting) so that
   // Windows displays the text correctly regardless of the HWND hierarchy.
