About the Unicode Encoder & Decoder

Unicode escape sequences represent characters using their code point in hexadecimal notation, for example \u00E9 for the letter e with an accent. Developers use these in source code, configuration files and data formats where non-ASCII characters need to be safely embedded. This free tool converts text to escape sequences and back entirely in your browser.

Frequently Asked Questions

Is this tool completely free?

Yes. The tool is 100% free to use with no registration, no subscription and no usage limits.

You can use it as many times as you need for personal or commercial projects without any cost.

We believe developer and productivity tools should be accessible to everyone without paywalls.

When would I use Unicode escape sequences?

They are useful when you need to include special characters in source code or configuration files that only support ASCII.

JavaScript, Java, Python and JSON all support \uXXXX syntax for embedding Unicode characters safely.

Escaping also helps when transmitting text through systems that may corrupt non-ASCII bytes.

What does the encoder do to ASCII characters?

ASCII characters with code points 0 to 127 are left unchanged because they do not require escaping.

يتم تحويل الشخصيات التي تزيد عن نقطة الشيفرة 127 فقط إلى شكل \uXXXX في المخرجات.

هذا يحافظ على قابلية قراءة المخرجات مع ضمان هروب جميع الشخصيات غير ASCII بشكل آمن.
