If your string contains compound Unicode characters, take precaution when calling myString.slice(), myString.substring(), etc. 3.1 Escape sequences.

These functions perform replacements on certain characters as shown in the table futher down the page and described briefly here: The JavaScript escape function replaces most punctuation symbols with the equivalent hex-codes, but was found to be inadequate when it came to UNICODE character encoding and has been superseded by the encodeURI function.; The encodeURIComponent function is an ...

Dec 09, 2019 - In Javascript, the identifiers and string literals can be expressed in Unicode via a Unicode escape sequence. The general syntax is \uXXXX, where X denotes four hexadecimal digits. For example, the letter o is denoted as ‘\u006F’ in Unicode. Hence, to write the letter “foo” in Unicode, ...

Enter an escaped JavaScript string, and the unescaped version will be displayed accordingly.

A Unicode code point escape \u{···} contributes the UTF-16 encoding of its code point (one or two UTF-16 code units). Template literals: In template literals, escape sequences are handled like in string literals. In tagged templates, how escape sequences are interpreted depends on the tag function. It can choose between two interpretations: Unicode was started in 1987, by Joe Becker (Xerox), Lee Collins (Apple), and Mark Davis (Apple).The idea was to create a universal character set, as there were many incompatible standards for encoding plain text at that time: numerous variations of 8-bit ASCII, Big Five (Traditional Chinese), GB 2312 (Simplified Chinese), and more. 4-digit Unicode escape sequences.
