Unicode Compatibility Checker

Will My Fancy Text Display Everywhere?

Paste any styled text above to see what share of it is special Unicode. As a rule of thumb: under 10% special characters is very safe, under 40% is mostly safe, and above that you risk empty boxes on older devices.

Quick Compatibility Guide

  • Bold, italic, cursive — excellent everywhere, including old phones.
  • Fraktur and blackletter — good on all modern devices.
  • Bubble and enclosed letters — good; very old phones may show boxes.
  • Fullwidth (vaporwave) — good on modern devices.
  • Zalgo glitch text — risky; can look broken and some apps trim it.

Tips for Maximum Compatibility

  • Test on the target app before posting something important.
  • Keep critical info plain — links, phone numbers, and instructions should stay in normal text.
  • Prefer simple styles for bios and usernames; save decorative ones for captions.

Frequently Asked Questions

Why do some characters show as empty boxes?

The dreaded box means the device’s font lacks that glyph — a missing character, not broken text. Switching to a simpler style fixes it.

Which styles are safest?

Bold, italic, and cursive variants of the Mathematical Alphanumeric Symbols block are supported virtually everywhere.

iPhone vs Android — any difference?

Both handle common styles well. Very new or obscure Unicode characters may appear on one before the other after OS updates.
