This has quite a lot of fall out. But the majority of it is just type or UDL substitution, where the changes just fall through to other function calls. By changing property key storage to UTF-16, the main affected areas are: * NativeFunction names must now be UTF-16 * Bytecode identifiers must now be UTF-16 * Module/binding names must now be UTF-16
