Most bold buttons apply rich-text formatting that only survives inside that one app — Instagram's bio field strips it back to plain text on paste. The bold letters here are separate Unicode characters, not formatting, so they paste in looking exactly the same everywhere.
Bold (serif) has the small decorative strokes you'd see in a textbook heading. Bold Italic leans the letters. Sans Bold is the clean, strokeless look you'd get from a heavy modern sans-serif. Same weight, three different personalities.
Unicode only defines a dedicated digit set for plain Bold, not for Bold Italic — so numbers are left as regular digits rather than faked with a mismatched glyph.
This tool maps your letters onto the Mathematical Alphanumeric Symbols block — a section of Unicode that includes complete, ready-made bold, bold italic, and sans-serif bold alphabets. Because every character is a genuine code point rather than a formatting flag, the bold look survives copy-paste into bios, comments, and chats that strip normal rich-text formatting.
Serif Bold has small decorative strokes — a classic, editorial feel. Sans Bold is clean and strokeless, closer to a modern app's UI bold. Bold Italic leans the letters for motion or emphasis on a single word inside a sentence. Try your text in all three before picking — the right one usually depends on the font already around it.
