Fonts, not files

Why fancy letters show as boxes

The hollow rectangle — sometimes called tofu — means the device has no font containing that character. The text is correct; the viewer simply cannot draw it. Here is why it happens and how to choose styles that avoid it.

Fancy fonts are characters, not fonts

A "fancy font" generator does not change the typeface. It swaps each letter for a different Unicode character that happens to look styled — mathematical bold 𝐀 instead of A, for example. Those characters live in less common Unicode blocks, and a device only shows them if one of its installed fonts covers that block.

Who sees boxes

Modern iPhones and Android phones cover the mathematical alphabets and most symbols. Older Android builds, some smart TVs, game clients with their own compact fonts and some desktop browsers without emoji fonts are the usual places a character goes missing. Game fonts are the strictest, which is why game pages on this site lead with the safest styles.

Safest to riskiest

Bold, sans and monospace letters — covered almost everywhere since 2015.
Script, Fraktur and double-struck — very wide coverage, a few game fonts miss them.
Text symbols (★ ♛ ♡ ⚜) — reliable; they predate emoji.
Emoji — appearance varies by device and some games strip them.
Combining marks and enclosing rings (the ⃝ around a 🦋) — the first to break on older devices.
Rare scripts used for shapes (Javanese ꧁꧂, Balinese ᭄) — common in gaming but absent from many desktop fonts.

How to check before you paste

Paste the styled text into the Compatibility Lab. It flags combining marks, enclosing rings, emoji, variation selectors and rare-script characters, and gives you a plain fallback. Then test in the real app on a friend's phone if the name matters.
