Playlist with emojis in title not showing up on friends iPad

[PW_]

Hi there // I have a playlist called 🍉🍉💥🌈🍣🍣🍣🍆🍆🍒2017 where I save my favourite tracks / and my friend follows me on his iPad // but under my Public Playlists on his iPad, it is not listed.  It's definitely public as I've been able to share it via text to other friends' iPhones.  Think there might be a bug there:) Many thanks!
