Yep, perfectly typable. Though I did have to look up the deadkey for ˚ as it's not a diacritic I use often (Option-K on the Mac OS X US Extended keymap; on Windows or Linux US International keymaps you can do it without a deadkey as Right-Alt W, or on the Mac US keymap as Option-A).

I highly recommend that people use and learn the "extended" or "international" keymaps on their system, so they can learn how to type these sorts of characters easily. As more and more systems are Unicode enabled, and you interact with more people internationally who would prefer their names to be spelled properly, it's a useful skill to have (and doesn't really take much work).
