title: How can I convert a 4-byte string into an unicode emoji?
body: <p>A webservice i use in my Delphi 10.3 returns a string to me consisting of these four bytes: F0 9F 99 82 . I expect a slightly smiling emoji. <a href="https://www.compart.com/de/unicode/U+1F642" rel="nofollow noreferrer">This</a> site shows this byte sequence as the UTF-8 representation of that emoji. So I guess i have a UTF-8 representation in my string, but its an actual unicode string? How do i convert my string into the actual unicode representation, to show it, for example, in a TMemo?</p>
