Except that you shouldn't use the full unit symbols for temperatures; they're "compatibility characters" and exist only to support round-tripping with certain CJK encodings (that is to say, so you can convert a text from EUC-JP to Unicode and back to EUC-JP, and have the same text). When composing a text in Unicode which is not required to be compatible with a specific text encoded in a different character set, you should always use the two separate symbols.
