How bold text works where there is no bold button
Instagram, X, LinkedIn posts and many profile fields do not have formatting options. This generator gets around that by swapping each letter for a look-alike character from Unicode's "Mathematical Alphanumeric Symbols" block, which contains bold, italic and script versions of the Latin alphabet and digits. Because they are real characters rather than formatting, they stay bold wherever you paste them.
Use bold for a headline, a call to action or a key phrase, not for whole posts. Screen readers may read these characters oddly or spell them out letter by letter, so people who use assistive technology may struggle with them, and search engines and in-app search may not match them to normal words. Accented letters have no bold version, so they stay plain. On LinkedIn, a bold first line is a popular way to stand out in the feed.
