Social Text Formatter

They're symbols, not fonts. A 'fancy font' generator doesn't change your typeface — it swaps each letter for a look-alike character from a different Unicode block (𝗮 is a different code point than a). Because the styling lives in the characters themselves, it travels with the text when you copy and paste, which is why it survives into Instagram or LinkedIn where real custom fonts don't. The trade-off is that the text is no longer plain letters, so treat it as decoration for short phrases, not body copy.

That's a missing-glyph fallback. When an app or older device doesn't have a glyph for a rarer Unicode style (some scripts and decorative blocks), it renders a box (▯) or question mark instead. Sans-serif bold and italic are the most widely supported; bold script, fraktur and double-struck are the most likely to break on older Android keyboards or low-end devices. Always preview on a phone before you post, and keep the safe styles for anything that matters.

Yes. Neither editor has a bold button because both are plain-text by design, but both render Unicode. Generate the bold text, copy it, and paste it straight into the bio field — the bold survives. Keep it to one emphasised phrase rather than a whole bold bio, since a wall of bold reads as shouting and is harder for screen readers. Links and @handles should stay in plain characters so they remain tappable.

Bold Unicode (𝗯𝗼𝗹𝗱) is for emphasis and hooks — the first thing a reader's eye lands on. Italic Unicode (𝘪𝘵𝘢𝘭𝘪𝘤) signals nuance: titles, product names, quotes and wry asides. Both come in sans and serif variants, and there's a combined sans bold-italic for text that's both. The rule is the same for each: use them on a single word or phrase, never for full paragraphs, and never on links or hashtags.
