Question

I\'d like to display the \"Open Lock\" character in my HTML link text.

If I do it directly it shows up correctly with 🔒<

Answer 1

Following script should convert UTF32 hex values to UTF16 pairs

function toUTF16Pair(hex) {
  hex = hex.replace(/[&#x;]/g,'');
    var x = parseInt(hex, 16);
    if (x >= 0x10000 && x <= 0x10FFFF) {
        var first = Math.floor((x - 0x10000) / 0x400) + 0xD800;
        var second = ((x - 0x10000) % 0x400) + 0xDC00;
        return {
            first: first.toString(16).toUpperCase(),
            second: second.toString(16).toUpperCase(),
          combined: '\\u'+first.toString(16).toUpperCase() + '\\u'+second.toString(16).toUpperCase()
        };
    } else {
        return {}
    }
}
