What are Unicode bold characters?
Unicode bold characters are special mathematical symbols that visually appear as bold letters and numbers. Unlike regular bold formatting that depends on application support, these characters are actual Unicode code points that display as bold text anywhere Unicode is supported. They're part of the Mathematical Alphanumeric Symbols block (U+1D400βU+1D7FF) originally designed for mathematical notation.
These characters work on platforms that don't support traditional text formatting, such as social media bios, usernames, text messages, and comments. When you paste ππ¨π₯π πππ±π into a plain text field, it retains its bold appearance because each character is a distinct Unicode symbol rather than formatted regular text.
Tool description
