Convert text to Unicode escape sequences or decode them back.

How to Calculate

Unicode escape represents characters as code points in the \uXXXX format. Common use cases: • Representing special characters in source code • Encoding non-ASCII characters in JSON data • Internationalization (i18n) tasks Formats: • Basic Multilingual Plane (BMP): \uXXXX (4-digit hex) • Supplementary characters: \u{XXXXX} (variable length) • ASCII characters (0-127) are not converted.
