Is it possible to export Unicode characters from supplementary planes (above Plane 0), i.e. those that need more than 2 bytes of storage? They seem to be silently ignored (normally a replacement character such as '?' is shown for unsupported code points).
A simple test shows that small value code points are OK but longer ones are ignored. This should show 2 smiley faces:
var editor =
"Smiley face OK: \u263A Smiley ignored: \uD83D\uDE0A"
Any comments/suggestions would be welcome.
