In this case, I was lazy and I opened KCharSelect (KDE4). I searched for 2122 
and it showed this information:

	Character: ™ U+2122
	Name: TRADE MARK SIGN

	Annotations and Cross References
	Approximate equivalents:
	 * <super> T U+0054 LATIN CAPITAL LETTER T M U+004D LATIN CAPITAL LETTER M

	General Character Properties
	Block: Letterlike Symbols
	Unicode category: Symbol, Other

	Various Useful Representations
	UTF-8: 0xE2 0x84 0xA2
	UTF-16: 0x2122
	C octal escaped UTF-8: \342\204\242
	XML decimal entity: &#8482;

The UTF-8 representation is what we're interested in. The difference is one is 
encoded in hex and the other is encoded in octal (that is, 0xE2 = 0342).

There must be many other tools that show the UTF-8 representation in octal 
given the Unicode codepoint. The UTF-8 encoding itself is specified in RFC 
3629. See http://en.wikipedia.org/wiki/UTF-8 for a table on how the encoding 
is done.

Another way of doing this is to use an UTF-8 shell and type:
$ echo ™ | od -tc
0000000 342 204 242  \n

If your shell is not UTF-8 capable, you can still type any valid character in 
your encoding and convert to UTF-8:
$ echo ™ | iconv -t utf-8 | od -tc
0000000 342 204 242  \n
