You send a styled name and a friend says it looks totally different — or shows as boxes. Same characters, two different sets of fonts drawing them.
Because each phone draws the styled characters with its own fonts. iPhone uses Apple’s San Francisco with a limited fallback; Android uses the Noto family (“no more tofu”), which covers more of the styled-character range. So the same string can look slightly different in shape, or render on Android while boxing out on an iPhone — or box out on an old Android that predates the coverage. Your text isn’t broken; the reader’s device is choosing the picture.
A styled letter like 𝕄 is a single Unicode character. Neither phone has a “fancy font” installed for your whole message — each one reaches into its font library to find a picture (a glyph) for that character. Apple and Google ship different libraries:
Because the glyph shapes and coverage differ, the same styled word can look a little different on each — or appear on one and box out on the other.
The decorative styles (fraktur, double-struck, obscure symbols) are where the gap shows most. Modern Android usually draws them via Noto; a strict iPhone may box them; and an old Android that never received the newer Noto coverage will box them too. So “it’s broken for some people” almost always means those people are on a device without a glyph for that character — not that you did anything wrong.
Stick to the widely-covered styles — bold, italic, small caps, monospace — which render nearly identically on both platforms. Save the decorative styles for throwaway flair, keep load-bearing words readable, and if a style matters, test it on a second device (an older Android is the toughest case). More in why fonts show as boxes.
Pick a widely-supported style and it’ll look the same on iPhone and Android. Type once, copy, paste anywhere.

A box means that person’s device has no glyph for the character. Modern Android draws most styles via Noto; a strict iPhone or an old Android may box the decorative ones. It depends entirely on the viewer’s device, not your text.
Bold, italic, small caps and monospace are covered on both and look nearly identical. Fraktur, double-struck and obscure decorative styles are where the two platforms diverge most.
The reader’s phone. The sender’s device stores and sends the same Unicode characters; how they look is decided by whichever fonts the reader’s device uses to draw them.
