Unicode Escape Converter

In JavaScript, some configs, and logs, non-ASCII characters often appear as \uXXXX escape sequences. Converting those escapes helps when an API shows encoded strings but the UI should show real characters.

Common uses

When front-end source or JSON shows fragments like \u4e2d\u6587, this tool restores them to readable text. You can also turn plain text into escapes for ASCII-only pipelines.

After input pauses, it tries to detect plain text vs escape sequences. Supplementary-plane characters may involve surrogate pairs — after copying, confirm display in the target environment.

Tips

  • Mojibake is not always a Unicode-escape issue — it can be UTF-8 / GBK mismatch; check the source system.
  • Pair with the UTF-8 hex tool for a fuller encoding debugging path.
