//     - EStdKeyDevice11 0xCA  E-accent circumflex    Northeast

//     - EStdKeyDevice12 0xCB  E-umlaut               Southeast

//     - EStdKeyDevice13 0xCC  I-accent grave         Southwest

//

//   While these ought to be vaguely acceptable in certain parts of a URL,

//   they are also used by some navigation drivers as our "diagonal event"

//   codes so turn up as the user navigates the cursor. Because of this,

//   today, we prevent them from being inserted as characters. There's

//   a second set of code ranges (in the 0x8XXX range) that's also defined

//   for these events; if the driver writers ever manage to get all of

//   the navigation drivers using this "out-of-band" range, we can

//   eliminate filtering the ISO-Latin-1 range of characters that we

//   do here.
