Zero Width Space (U+200B)
The Zero Width Space (U+200B) is a Unicode character that takes up zero visible width — text flows past it as if it were not there. It is the building block of nearly every invisible text trick on the internet.
The character itself
U+200B has no visible glyph in any font. It exists purely as data, which is why fields, forms, and validation systems count it as a real character.
Common uses
Blank usernames and nicknames in games and apps, invisible line-break hints for long URLs, and preventing words from sticking together in layouts.
How to copy it
Use an invisible character generator to copy U+200B reliably — typing it by hand is impractical since you cannot see it.
Frequently asked questions
What is the difference between U+200B and a normal space?
A normal space (U+0020) has visible width and gets trimmed by platforms. U+200B has zero width and is treated as content, so it survives.
Is U+200B supported everywhere?
It is a standard Unicode character supported by virtually all modern apps, fonts, and systems.
Can I type it directly?
On most keyboards, no. Use a generator tool to copy it, or paste it from a document that already contains it.
