a$ = chr(56000) : b$ = chr(42892)
print (asc(a$)) // Returns -1
print (asc(b$)) // Returns 42892

I dont think its a bug - AppGameKit hasnt been designed to just not go beyond 55295

Im not really sure what the signifies and why you would want to go beyond..

I can't see a reason why the reverse value shouldn't be designed to be accessable if chr(56000) is.

The range 0xD800 to 0xDFFF (55296 to 57343) have been designated as invalid Unicode values as they are reserved for UTF-16 special cases. They do not represent any characters.
