Remove the invisible characters from your text, from bidi controls and control characters to unusual spaces, with settings that keep Urdu joiners safe.
Quick Answer
The Urdu Invisible Character Cleaner strips invisible characters out of your text. It can remove bidirectional controls, control characters, zero-width characters, and turn unusual spaces into a normal space. The defaults leave the Urdu joiners alone, since they matter for how letters connect. Everything runs in your browser.

What the Urdu Invisible Character Cleaner Does
The Urdu Invisible Character Cleaner removes invisible characters from your text and returns a clean copy. It can take out bidirectional controls, control characters, and zero-width characters, and it can turn unusual and non-breaking spaces into an ordinary space. You choose which groups to act on.
The defaults are set to be safe for Urdu, so the joiners that control how letters connect are left alone unless you ask for them to go.
Everything runs on your own device. Your text is never uploaded or stored, so it stays private while you clean it.
How to Clean Text
- Paste your text. Enter or paste the text you want to clean.
- Choose the groups. Pick the bidi controls, the spaces, the control characters, or the zero-width characters.
- Read the clean copy. The cleaned text appears, with a count of what changed.
- Copy or download. Copy the clean text, or save it as a file.
The Groups You Can Remove
The cleaner works in groups. Bidi controls and directional marks steer direction. Control characters and the soft hyphen are non-printing. Unusual and non-breaking spaces are odd whitespace that can be turned into a normal space. Zero-width characters take no space and include the Urdu joiners.
Keeping Urdu Joiners
The zero-width joiner and non-joiner change how Urdu letters connect, so removing them can change how a word looks. That is why the zero-width option is off by default. Turn it on only when you know the joiners are not needed in your text.
Fixing Spaces
Rather than delete an unusual or non-breaking space, the cleaner turns it into a normal space, so words stay separated. This keeps the text readable while removing the odd widths and the non-breaking behaviour that can cause layout problems.

Who Uses This Cleaner
Developers use it to sanitise input. Editors use it to tidy pasted text. Anyone who found invisible characters uses it to remove them.
Accuracy and Limits
The cleaner acts only on the groups you choose, by code point, and keeps everything else. It turns odd spaces into a normal space rather than deleting them, so word breaks are kept. It does not touch the ordinary space, tab, or line break.
Good to know: to see what is present before cleaning, use the hidden character finder.
Your Data Stays Private
The cleaner runs fully in your browser with standard web technology. Your text is not uploaded or stored, and it is not sent to any analytics service. Only your star rating is sent, to record the tool’s rating. When you close the page, your text is gone.
Frequently Asked Questions
What does the Urdu Invisible Character Cleaner do?
It removes invisible characters from your text by group, bidi controls, control characters, and zero-width characters, and turns unusual spaces into a normal space.
