What is Double-Struck text and will it work in my app?
Double-Struck text is ordinary text converted to look-alike letters, so it works anywhere plain text is accepted without installing a font. Support level: works in most apps. Expect this to work almost everywhere. The characters used here are common, so only very old devices or stripped-down apps will have trouble. If an app draws empty boxes, that app is missing the characters this style uses, so the style itself is fine but that app cannot display it.
How Double-Struck text works
Each letter is swapped for a different Unicode character that has the same shape. You type ordinary text and the style is applied for you.
Because the output uses standard Unicode characters rather than a font, it can be pasted into any app that accepts plain text. Nothing needs to be installed on either side.
It is usually described as outline or hollow, which is how people searching for it tend to look.
Category: Outline. Tagged as outline, hollow, blackboard.

Where Double-Struck text works
Expect this to work almost everywhere. The characters used here are common, so only very old devices or stripped-down apps will have trouble.
The apps people paste styled text into most often behave like this:
- Snapchat works: accepts styled text in the bio, which is where most people use it.
- Instagram works: keeps the characters in bios and captions, but not inside a username field.
If you need a result that cannot break, pair this style with a plain-text fallback. Some apps let you paste an alternative that appears only when styled text is not rendered, which is worth doing for a profile name other people have to read.
When to use Double-Struck
This style suits a nickname where bold would be too heavy, a poster title with a light look and text that needs to sit on a dark background. It is built from Unicode characters rather than a font, so the result stays selectable and searchable in most apps, and it will not change shape when someone else views it.
It will not work for anything that needs to be read reliably, such as a support message, an address or a link. Styled text is for display, where a reader is looking at it rather than searching through it.
For something more legible, try Bold, Old English, Cursive Script.
Questions
How do I use Double-Struck?
Type your text, copy the result and paste it where you want it. No font install is needed because the result is made of Unicode characters.
Where does Double-Struck work?
Works in most apps. If an app shows empty boxes, its font lacks those characters.
Is my text saved anywhere?
No. The text is styled in your browser and is not sent to or stored on our server.
Why does Double-Struck text look like boxes in some apps?
The style uses Unicode characters rather than a font, so an app shows them correctly only if the device has a glyph for each one. Missing characters fall back to an empty box.
Can I use Double-Struck text commercially?
Yes. The characters come from the Unicode standard rather than from a licensed typeface, and the generated text is yours to use on any platform.
What is the difference between Double-Struck text and a font?
A font changes the shape of ordinary letters, so the text stays readable and searchable but needs the font installed. Double-Struck text replaces each letter with a different Unicode character, so it works anywhere plain text is accepted without installing anything.
