🥰 isn't recognised as an emoji.

[gianzellweger]

Since I haven't found a more convenient way to test emojis in bulk, this is the only one I found so far. I see no reason for it not being an emoji.

Steps to reproduce

fn main() {
    assert!(unic_emoji_char::is_emoji('🥰'));
}

That emoji was added in Unicode 11, this crate only supports Unicode 10. (Development of this crate has stopped, seemingly.)

[crlf0710]

I'd suggest moving to the unicode-properties crate (which is currently used by rustc) as a replacement if you need newer version data.

Disclaimer: I created that crate and handed it over to unicode-rs :)
