I don't understand the previous two replies, since character 160 has the same meaning in Latin-1 as it does in Unicode. Namely, none. That is a C1 control code with no defined meaning.
In the Windows 1252 character set, the C1 zone has extra characters in it, making it a super-set of Latin 1. I guess 160 (0xA0) is the non-breaking space character.
So, the code appears to be converting from a character set where 0xa0 means A-hat, which is 194 in Latin-1.
Hmm, perhaps the resulting UTF-8 is being treated as two characters later. A0 will be encoded as C3 80, which if re-displayed as Windows 1252 is A-tilde then the wanted non-breaking space. If your note was a typo (tilde instead of angle hat), that's what's happening.
