Use Unicode Converter when the issue is character encoding, escaping, or internationalized text. If you are troubleshooting encoded URLs, continue with URL Encoder/Decoder. If you are working with encoded payloads or transport-safe strings, pair it with Base64 Encoder/Decoder.
No-upload workflow: multilingual text, escaped strings, and sensitive content stay in your browser while you inspect and convert them.
