//
// Example: @Char ( 128512 ) ==> 😀

Char (

	If ( codePoint > 65535
	and codePoint < 1114112 ; // ≤10FFFF

		// transform into a pair of UTF-16 Surrogates
		Mod ( codePoint - 65536 ; 1024 ) + 56320 & // +DC00 Low
		Div ( codePoint - 65536 ; 1024 ) + 55296 ; // +D800 High

		// else, use as is
		codePoint
	)

)

Converts UTF-32 into UTF-16 to then let the original function handle the code point properly.

Should work well in all FMP versions.
