How to use this tool
Encoding uses \uXXXX for BMP characters and \u{XXXXX} for supplementary code points. Decoding accepts both forms and valid surrogate pairs.
Limits and behavior
Only Unicode escapes are decoded. Other escape sequences remain literal. Malformed escapes, out-of-range values, and unpaired surrogates are rejected. Input is limited to 1 MB and output to 3 MB. No input content is saved by CraftAI.

Does this convert the text into a secure cipher?
No. Unicode escaping is a reversible textual representation, not encryption.
