This is similar to the design of supplementaryĪll changes described are relative to the ECMAScript Supplementary characters are then interpreted as atomic entities with theirĬorrect Unicode semantics, just like characters in the Basic Multilingual Plane.

The basic idea is to keep the existing text representation,īut change operations that interpret text to be based on Unicode code points. This article proposes a set of ECMAScript specification changes that enableĬorrect processing of supplementary characters while maintaining compatibility On code units separately, so that it cannot correctly interpret supplementary Some text processing functionality in ECMAScript itself is defined to operate This to build applications that support supplementary characters. UTF-16 to exchange text with their ECMAScript subsystem.

Have surrounded ECMAScript implementations with text input, text rendering,ĭOM APIs, and XMLHttpRequest with full Unicode support, and generally use full Support supplementary characters, as the encoding of source text and strings,Īnd implementations generally allow supplementary characters to be used. The Unicode encoding form designed to extend the original 16-bit encoding to The ECMAScript standard specifies UTF-16, Outside the 16-bit code space originally envisioned for Unicode and require In the process, some details have changed for example, source code is now interpreted as a sequence of Unicode code points rather then UTF-16 code units, Unicode mode and compatibility mode of regular expressions have been integrated in the specification using parameterized productions, and the argument to codePointAt is coerced to an integer before use.ĮCMAScript, the standard underlying JavaScript, has so far been ambivalentĪbout supporting supplementary characters, those Unicode characters that are

Update July 2015: This proposal has been integrated into the ECMAScript ® 2015 Language Specification, which has been approved as the 6 th edition of standard ECMA-262.
