About this tool

Type or paste text and it’s converted to Unicode Mathematical Double-Struck characters automatically, ready to copy into any app.

Frequently asked questions

How does this actually work?
It maps each letter and digit to its Unicode Mathematical Double-Struck ("blackboard bold") equivalent β€” the same style used for number-set symbols like ℝ and β„€ in mathematics.
Why do some letters look different from the rest?
C, H, N, P, Q, R, and Z reuse older, pre-existing Unicode symbol characters (β„‚, ℍ, β„•, β„™, β„š, ℝ, β„€) instead of the newer Mathematical Alphanumeric block, because Unicode deliberately left those seven code points unassigned there to avoid duplicating symbols that already existed.
Can I preview other styles without leaving this page?
Yes β€” the gallery below the text boxes lets you switch the live preview to any other Font Styles tool's style, and pin favorites for quick access next time.
