What's the UITableView index magnifying glass character?

In Apple's iPhone apps (like Contacts), they have a nice magnifying glass icon at the top of the table view index. Since the table view index API is character-based, I assume that this magnifying glass is a Unicode character. So far I've resorted to placing a question mark character there, but that looks lame.

Can anyone tell me what character the magnifying glass is?

Returning UITableViewIndexSearch as section index title (same as @"{search}") also works.

In Swift you would use UITableView.indexSearch.

@"{search}" FTW.

Return that title and it's magically replaced by the correct glyph.
