0x7F is a DELETE control character. It is apparently "skipped" (not rendered, does not take up a column) in most Cocoa apps, although it clearly exists.

For some crazy reason, shift + up arrow + backspace will generate one of these. I had a habit of deleting a line of text and starting over by holding shift and up arrow, followed by a backspace, and these got stuck into all sorts of data/text I work with. Google results, IRC/AIM chats, emails, etc.

Filed in 2007. Closed in 2012, told to watch release notes in future.

Still reproducible. Happens to be 0x08 (BACKSPACE) on current Mac. Tried to reopen 2015, asked to refile due to age.

Now is rdar://21783531
