Cursive unicode is the most requested style for social bios, and also the one that fails most often. Some platforms truncate it, and a few strip characters they do not recognise.
Test the result in the exact app before you commit. Cursive Text Generator previews the string before you copy it, so you can paste it into a draft and check on mobile.
Keep a plain-text backup of your bio. If the platform updates its character handling, you can restore it in seconds.
