How Unicode-encoded emoji is displayed on the front-end

Call this method

function Findsurrogatepair (point) {  //  assumes point > 0xFFFF  var offset = Point -0x10000,      = 0xd800 + (offset >>),      = 0xdc00 + (offset & 0x3ff);   return [Lead.tostring (+), trail.tostring (+)];}

Example: The Unicode encoding of a emoji is u+1f339, the previous u+ is replaced with 0x, that is, u+1f339-->0x1f339, to the above function

Findsurrogatepair (0x1f600)

You will then receive an array

The two items in the array are stitched together into: [' \ud83d\ude00 '], and the resulting results can be displayed directly on the front end.
