Use this tool to safely include extended Unicode characters in query strings, API calls, or embedded scripts. It’s also helpful for debugging URLs, encoding content in JavaScript/JSON, or building obfuscation layers for technical content.

Useful Tools & Suggestions:

If you’re cleaning up text before encoding, Replace Text is perfect for fixing or swapping out anything tricky. And once your data’s ready, Add a Suffix to Text Lines can help tag or organize each piece of the output.
