It's already UTF-8 because it's a 'string'. :)

import std.stdio;

void main() {
     auto s = "\u1234";

     foreach (codeUnit; s) {
         writefln("%02x %08b", codeUnit, codeUnit);
     }
}

The output has three code units for "U+1234 ETHIOPIC SYLLABLE SEE", not 
two bytes:

e1 11100001
88 10001000
b4 10110100
