`[NSString UTF8String]` sometimes returns null (it's documented as such), and when it does, zed crashes in `window::insert_text`. I'm running into this sometimes when using alt-d to delete forward. It usually only happens with multiple cursors, but sometimes with a single cursor. It *might* only happen when using the "Unicode Hex Input" keyboard 'Input Source' (which I started using to avoid entering weird characters in zed when using emacs meta keybindings that I haven't defined in zed). When using the US English input source, alt-d always results in a call to `insert_text`. When using the Unicode Hex Input source it usually doesn't, but when it does `text.UTF8String()` returns null. `text` isn't null. `[text length]` returns 1. `[text characterAtIndex: 0]` seems to always return `56797` (an undefined utf-16 codepoint). Release Notes: - Fixed crash on mac when deleting with alt-d
