Generate and copy invisible characters
The Invisible Character tool allows you to easily generate, copy, and inspect hidden Unicode symbols. Whether you need to send an empty message, create an invisible name in a game, or format a document with specific spacing rules, this tool provides instant access to the most common blank characters.
Because the tool runs entirely locally in your browser, your clipboard data and text inputs are never uploaded to a server. You can safely paste sensitive text into the checker to scan for hidden formatting marks without worrying about privacy.
Types of blank text and spaces
The Unicode standard includes thousands of characters, but not all of them are visible letters or numbers. Some are designed specifically for spacing, formatting, or script-specific fillers. When you need an empty character copy paste solution, it helps to know which symbol to choose:
Hangul Filler (U+3164): Originally designed for Korean typography, this character is widely treated as a standard letter rather than a space. This makes it the most popular choice for creating a blank space for name fields in video games and social media profiles.
Braille Pattern Blank (U+2800): This is technically a Braille character with no raised dots. Because systems treat it as a Braille letter rather than whitespace, it is often used when an app ignores messages that contain only regular spaces.
Zero Width Space (U+200B): A zero width space is a non-printing character. It has no width and is completely invisible to the eye, but it acts as a boundary between words. Web designers and writers use it to tell a browser where it is safe to break a long URL or a continuous string of text without forcing a visible space.
No-Break Space (U+00A0): Also known as a non-breaking space, this character looks exactly like a normal space but prevents text-rendering engines from breaking a line at that exact spot. It is useful for keeping units attached to numbers (e.g., "10 kg") on the same line.
Common uses for invisible characters
Gaming and social media profiles. Many online games and social platforms strip leading, trailing or repeated spaces from names. Characters like the Hangul Filler are not treated as spaces, so they are commonly used to create a blank-looking name or extra spacing. Each platform has its own rules and some remove these characters, so check the result and follow the platform's naming policy.
Empty messages and comments. Typing only regular spaces usually doesn't produce a blank message or comment, because apps trim them. A Braille Pattern Blank counts as a character, so it is often used for this, although some apps may still remove or reject it.
Advanced text formatting. Writers and developers frequently use zero-width characters to control how text flows on a screen. If you are building a website and have a very long word that breaks the layout on mobile devices, inserting a zero width space allows the text to wrap cleanly.
How to detect hidden characters
Invisible characters are useful, but they can also cause frustrating issues. If you are a programmer or data analyst, a stray zero width space copied from a document can break your code, cause database queries to fail, or make passwords invalid. Because these characters are invisible, they are nearly impossible to spot in a standard text editor.
To solve this, our tool includes a built-in text checker. Simply paste your text into the "Check for hidden characters" box at the bottom of the page. The tool scans your input and reveals any hidden characters by replacing them with their Unicode hex value in brackets (for example, [U+200B]). This makes it easy to find and remove problematic formatting marks.
If you are working with complex text formatting, you might also find our Character Counter useful for tracking exact text lengths, or our Symbols and Fancy Text Generator tools for finding other unique Unicode characters.
