Mostly yes — but iOS is picky in one specific way that turns the fancier styles into empty boxes. Here’s what renders and what to avoid.
Yes, for the common styles. iPhones ship fonts that cover bold, italic, sans, small caps and monospace, so those copy-and-paste fine into names, bios and Messages. The catch is that iOS is strict about fallback: if a style uses characters the system font doesn’t have, iOS often draws an empty box (□) instead of borrowing a glyph from another font. So the most decorative styles — fraktur, double-struck and obscure symbols — are the ones that break on iPhone.
These map to Unicode blocks that Apple’s system fonts cover, so they render on every current iPhone and paste cleanly into Instagram, TikTok, Discord, Messages and Notes:

When a character isn’t in iOS’s font, the iPhone frequently doesn’t substitute another font — it just draws the .notdef box (□). Android leans on its Noto fonts to avoid this; iOS is less forgiving. So the styles most likely to box out on iPhone are:
Remember the box is drawn by the viewer’s iPhone, not yours — so your text can look perfect to you and broken to a friend. See why fonts show as boxes.
Styled text works in display names, bios, captions and messages. It does not work in @username / handle fields, which are ASCII-only across apps. Accented letters follow the same rule as everywhere — most styles leave them plain (see why fancy text removes accents).
Generate a bold, italic or small-caps style — the ones iOS renders everywhere — then copy and paste it straight into any app.

Yes for the common styles. iPhones render bold, italic, sans, small caps, monospace and usually script, because iOS ships fonts covering those characters. The more decorative styles (fraktur, double-struck, obscure symbols) can show as empty boxes because iOS rarely falls back to another font for a missing glyph.
Because iOS does not substitute another font when the system font lacks a character — it draws the .notdef box instead. Styles built from rare Unicode blocks therefore box out on iPhone, especially on older iOS versions. The box is drawn by the viewer’s device, so the same text can look fine to you and broken to them.
Bold, italic, bold-italic, small caps and monospace are the safest, with script usually reliable too. Avoid fraktur, double-struck and heavily decorative styles if you need it to render on every iPhone.
Yes — Messages, Notes, Mail and most apps display styled Unicode fine, since it is ordinary text. Just avoid the rarest styles for recipients on old devices, and remember @handles stay plain.
Display-style name fields accept styled Unicode, but system identifiers (Apple ID email, phone) do not. As a rule, styled text works anywhere it is shown as a label, not where it is used as an address or handle.
