Invisible Space
An invisible space is a Unicode character that adds zero visible width — commonly mistaken for a regular space, but far more powerful: it survives trimming and displays as nothing.
Invisible space vs regular space
A regular space (U+0020) has width and gets trimmed by platforms. An invisible space (U+200B) has zero width and is treated as content.
Uses for invisible spaces
Blank names, hidden separators in words, preventing line-break issues in long URLs, and padding text without visible spacing.
How to copy one
Use an invisible character tool to copy U+200B reliably — you cannot type it on a standard keyboard.
Frequently asked questions
What is the Unicode code for invisible space?
The most common is U+200B (ZERO WIDTH SPACE). U+FEFF (BOM) and U+2060 (WORD JOINER) are alternatives.
Why does my invisible space get deleted?
Some apps strip zero-width characters. Paste two or three in a row, or use U+FEFF which some filters allow.
Is it a real space?
It is a real character with no visible width — not the same as the space bar, but often used in its place for invisible formatting.
