How do I copy and use 𝐒?
Use the Copy button above, paste the result into the field you want, and verify it before saving. Unicode support, fonts, moderation filters and character limits can differ between apps and devices.
Why can the same Unicode letter look different on another device?
The code point stays the same, but the receiving operating system or app chooses the font that draws it. Shape, weight, spacing or fallback rendering can therefore vary even when the copied character itself has not changed.
