Norman… no offense… but have you tried using \u1f60A in an RTF document?
it doesn’t do anything but print “f160a”
however
\\uc0\\u55357 \\u56832DOES result in a 
{\\rtf1\\ansi\\ansicpg1252\\cocoartf1404\\cocoasubrtf460
{\\fonttbl
\\f0\\fswiss\\fcharset0 Helvetica;
\\f1\\fnil\\fcharset0 Monaco;
}
\\f0 this is Unicode 1f60a [ \\u1f160a ] using Helvetica
\\f1 this is Unicode 1f60a [ \\u1f160a ] using Monaco
\\f0 \\uc0\\u55357 \\u56832 from Helvetica
\\f1 \\uc0\\u55357 \\u56832 from Helvetica
}if I mis understood what you tried to convey, please show me what I did incorrectly
