Text to Unicode Escapes
Encode every character of a string into a chosen Unicode-escape notation. Four formats are supported: U+XXXX (Unicode standard UCS notation), \uXXXX (JavaScript / Java / JSON escape), &#XXXX; (HTML numeric entity, decimal-style but you get hex here too — see html-encode for the decimal form), and %uXXXX (older JavaScript escape() style). Each code is rendered as four uppercase hex digits. Supplementary characters (above U+FFFF) are emitted as a surrogate pair so the \uXXXX form is round-trippable. Runs entirely in your browser.
