What the Urdu Unicode Control Character Cleaner Does
The Urdu Unicode Control Character Cleaner removes control characters from your text. These are the non-printing codes below the normal letter range, plus the delete code and the C1 codes, which do nothing visible but can break how text is stored, searched, and displayed.
Control characters are a different problem from the zero-width and format characters, which is why they have their own cleaner. You can keep line breaks and tabs, since those are control codes you usually want.
Everything runs on your own device. Your text is never uploaded or stored, so it stays private while you clean it.
How to Clean
- Paste your text. Enter text that may hold control characters.
- Choose what to keep. Decide whether to keep line breaks and tabs.
- See the change. The before and after previews show what was removed.
- Copy or download. Copy the cleaned text, or save it as a text file.
What a Control Character Is
Control characters are the code points that were meant to control devices rather than to be printed, such as the null, bell, backspace, and escape codes. They take no visible space but they are still stored in the text, and they can confuse programs that read it.
Keeping Line Breaks and Tabs
The line break and the tab are technically control characters, but they are ones you usually want to keep, since they shape the layout. The cleaner keeps them by default, and you can turn either off if you want a single unbroken line of text.
Where They Come From
Control characters slip in when text is copied from a file, a log, a terminal, or a database export. They are invisible, so you do not notice them until something breaks. Running the cleaner over pasted data is a quick way to be sure it is free of them.

Who Uses This Cleaner
Developers use it to clean data from exports and logs. Editors use it on pasted text. Anyone with text that behaves oddly uses it to strip control codes.
Accuracy and Limits
The cleaner removes the control code points exactly, and keeps line breaks and tabs when you choose to. It does not touch zero-width or format characters, which are handled by the invisible character cleaner, so you can use the two together for a full clean.
Good to know: the report counts each removed character, so you can confirm how many were taken out.
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.
