Your input is processed locally in your browser whenever possible. We do not store your data.
Flow
- Iterate through Unicode code points in the input text.
- Render each code point using escaped notation (\uXXXX or \u{...}).
- Return a transport-safe escaped string for code and JSON workflows.
Example
Worked example: café
- 1 Input text = café.
- 2 Character é maps to Unicode U+00E9.
- 3 Escaped output becomes caf\u00E9.
Escaped form can be pasted in JSON and JavaScript strings.
How
- Paste plain text containing non-ASCII or special characters.
- Choose escape style if options are shown.
- Copy escaped output for source code, JSON, or documentation.
Cases
- Prepare test fixtures with explicit code points.
- Escape user-generated text before embedding in source literals.
- Normalize strings for language/runtime compatibility testing.
Avoid
- Double-escaping already escaped strings.
- Mixing JSON escape needs with regex escaping needs.
- Assuming surrogate-pair characters fit in a single \uXXXX sequence.
FAQ
Does unicode escape send my input to a server?
No. Unicode Escape handles the input in your browser whenever possible, so routine conversions, previews, and copy actions stay on your device instead of being sent to Calctrove servers.
Does this keep plain ASCII characters unchanged?
Depending on mode, ASCII may stay plain while non-ASCII characters are escaped.
Should I use this for regex escaping?
No. Regex escaping is different, use Regex Escape for regular-expression-safe strings.
