numToChar with socking great numbers

[Fraser Gordon]

You need two numToChar calls:

numToChar(55357)+ numToChar(56832)

The Unicode engine will fix this with a new call that handles surrogate
pairs automatically and invisibly but numToChar will probably have to
retain the mod-65536 behaviour for compatibility.

Fraser
