Unicode escaped.
How it works
- Read each code point in the input string.
- Wrote printable ASCII as-is and every other code point as a backslash-u escape (a surrogate pair above U+FFFF).
- Escaping is lossless; decoding accepts backslash-u, backslash-u-brace and backslash-x forms.
Methodology
- Read the input text one character at a time.
- Apply the cipher or encoding transformation for the chosen direction.
- Return the transformed text with a short summary.
Usage
- Paste or type the text to convert.
- Choose Encode or Decode.
- Read the converted text and copy it.
Examples
These are examples, not current values: they use fixed inputs, while the interactive tool computes live results in your browser.
Encode a sample
{
"text": "café",
"direction": "encode"
}Decode a sample
{
"text": "caf\\u00e9",
"direction": "decode"
}Limitations
How the Unicode Escape works
Escape text to Unicode code-point escape sequences and decode them back. The transformation is a single deterministic pass, so the same input always produces the same output.
Frequently asked questions
- Is this cipher secure?
- No. Classical substitution and transposition ciphers are educational and are not suitable for protecting real secrets.
- Does everything round-trip?
- Reversible ciphers round-trip for alphabetic input; encodings that normalise case or drop characters document that in their notes.
