How Bold Text Works on Social Media
Mathematical Alphanumeric Symbols
These characters reside in the Unicode block starting at U+1D400. Because platforms like Instagram, X, and Facebook treat them as distinct characters rather than CSS styling, they stay bold wherever you paste them.
Screen Reader Considerations
Screen readers may read these symbols letter by letter (e.g. "Mathematical Bold Capital B"). Use bold text strategically for headlines and short emphasis phrases, rather than entire body paragraphs.
