Logic: when a key event is sent, `event.key` represents its printable value _or_ one
|
||||
of a large list of special values indicating meta keys/functionality. In addition,
|
||||
key events for compose functionality contain a value of `Dead` when mid-composition.
|
||||
I can't quite verify it, but non-English IMEs may also be able to generate key codes
|
||||
for code points in the surrogate-pair range, which could potentially be seen as having
|
||||
key.length > 1. Since `Fn` is one of the special keys, we can't distinguish by that
|
||||
alone.
|
||||
Here, key.length === 1 means we know for sure the input was printable and not a special
|
||||
`key` value. When the length is greater than 1, it could be either a printable surrogate
|
||||
pair or a special `key` value. We can tell the difference by checking if the _character
|
||||
code_ value (not code point!) is in the "surrogate pair" range or not.
|
||||
We don't use .codePointAt because an invalid code point would return 65535, which wouldn't
|
||||
pass the >= 0x10000 check we would otherwise use.
