Why boxes appear
A box usually means the selected system font does not contain a glyph for that Unicode character.

Fancy Text Compatibility Guide
Fancy text works in many Unicode text fields, but actual rendering can vary. A preview is helpful; the target app and device are the final check.
Why an app can change the result
Apps may filter characters, normalize input, apply their own fonts, or render the same text differently across versions.
A practical test
Copy one short sample, paste it into the exact field, save or preview it, and check another device when the text is important.
What the labels mean
Readable, Decorative, and Experimental describe structural risk. Safe mode filters lower-risk mappings; platform status remains Not device-tested until an exact field passes the recorded device procedure.

Quick answers
Why does fancy text show as squares?
The current font probably lacks the required glyph. Choose a Readable style or use plain text.
Do fancy fonts work on every device?
No guarantee is possible. Rendering depends on the character, font, app, operating system, and version.
