What is Heavy Zalgo Up Only text and will it work in my app?

Heavy Zalgo Up Only text is ordinary text converted to combining marks, so it works anywhere plain text is accepted without installing a font. Support level: check your app first. Some apps replace these characters with boxes or substitute a different emoji. If you need a guaranteed result, test it in the app you have in mind before relying on it. If an app draws empty boxes, that app is missing the characters this style uses, so the style itself is fine but that app cannot display it.

It will not work for anything that needs to be read reliably, such as a support message, an address or a link. Styled text is for display, where a reader is looking at it rather than searching through it.

For something more legible, try Bold, Old English, Cursive Script.
