How to use Escape Unicode
- 1. Paste the text to escape. Paste the Unicode text you want converted to escape sequences, particularly any characters outside the plain ASCII range.
- 2. Choose an Escape format. Choose an Escape format matching your target language: JavaScript's backslash-u for basic characters, the ES6 curly-brace form for characters beyond the Basic Multilingual Plane, CSS's backslash notation, or percent-encoding.
- 3. Copy the escaped string. Copy the escaped string and paste it directly into a JavaScript string literal, a CSS content value, or a URL where raw non-ASCII characters are not allowed.
When to use Escape Unicode
Escape Unicode rewrites non-ASCII characters as backslash or percent escape sequences in the format a specific language expects. It solves the moment a source file, config, or URL needs to represent a character without including the raw byte itself.
- Hardcoding a Unicode string in JavaScript source. A JavaScript file needs a string literal containing a special character, and some editors or linters prefer escaped sequences over raw non-ASCII bytes in the source file.
- Writing a CSS content property with a symbol. A CSS pseudo-element uses the content property to display an icon or symbol, and CSS's own backslash escape notation is required rather than the JavaScript or URL forms.
- Building a percent-encoded URL fragment. A URL needs a query parameter containing an accented character, and percent-encoding it here ensures the character survives being passed through a browser's address bar.
- Debugging a string that displays escape codes literally. A rendered page shows literal backslash-u sequences instead of the intended character, and comparing your expected escape format against the visible output reveals which format the parser expected.

About the Escape Unicode tool
Escape Unicode does its work locally, right in the browser. Quickly convert Unicode data to escape sequences. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the Unicode Tools collection on EditSafely, a set of 98 small, focused Unicode utilities that share the same instant, private workspace.
You can shape the output with the Escape format setting, and the result refreshes the moment you change it. A worked example further down the page shows exactly what the tool produces for a real input.
Running locally also makes the tool fast and dependable: results appear as you type or drop a file, there is no server outage that can take it down mid-task, and confidential data can be processed without a second thought.
Frequently asked questions
Does Escape Unicode cost anything?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
No data leaves your device. The whole tool is JavaScript that runs inside your browser tab, so there is no upload, no server-side processing and no log of what you did. If you disconnect from the internet after the page loads, it keeps working.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
Nothing to install and no account needed. Open the page in any up-to-date browser, including on a phone or tablet, and the tool is ready.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
