Make text bold with real Unicode characters that survive copy and paste, four bold weights, including sans-serif and bold italic.

The classic use is emphasis where no bold button exists: the first line of a social bio, a keyword inside a caption, a price or a deadline in a message, a section header in a plain-text note. Bold sans reads cleanest next to modern app fonts; the serif bold matches formal documents; bold italic is for emphasis inside already-italic text; bold script behaves like a cursive name in a heavy weight.
Because that attaches a formatting flag to normal letters, and the flag only survives where formatting is supported, paste it into a bio, a chat or a plain-text field and the bold vanishes. These characters are bold by design, so the weight is part of the text itself and travels with every copy and paste. The trade-off: they are different codepoints, so search and screen readers do not treat them as ordinary letters.
Same weight, different letterform tradition. Mathematical Bold (๐๐จ๐ฅ๐) keeps serif details on the letter shapes; bold sans (๐ฏ๐ผ๐น๐ฑ) uses geometric strokes without serifs. Next to the sans-serif fonts most apps use today, bold sans usually blends in better; serif bold stands out more and suits formal or editorial text.
Digits do: the bold digit block (U+1D7CE) is complete, so dates, prices and versions convert exactly. Punctuation does not, there are no bold commas, periods or question marks in Unicode, so they pass through unchanged. A bold sentence therefore keeps its normal punctuation, which is why short strings look best.
Same idea, independent implementation. LingoJam popularised Unicode text generators, and people often search for it by name. This tool maps the same Mathematical Bold alphabets from the Unicode standard, the output letters are identical, because there is only one correct bold alphabet. Nothing to install and nothing uploaded: the conversion runs in your browser.
