| ECMA Section: Source Text |
| Description: |
| |
| ECMAScript source text is represented as a sequence of characters |
| representable using the Unicode version 2.0 character encoding. |
| |
| SourceCharacter :: |
| any Unicode character |
| |
| However, it is possible to represent every ECMAScript program using |
| only ASCII characters (which are equivalent to the first 128 Unicode |
| characters). Non-ASCII Unicode characters may appear only within comments |
| and string literals. In string literals, any Unicode character may also be |
| expressed as a Unicode escape sequence consisting of six ASCII characters, |
| namely \u plus four hexadecimal digits. Within a comment, such an escape |
| sequence is effectively ignored as part of the comment. Within a string |
| literal, the Unicode escape sequence contributes one character to the string |
| value of the literal. |
| |
| Note that ECMAScript differs from the Java programming language in the |
| behavior of Unicode escape sequences. In a Java program, if the Unicode escape |
| sequence \u000A, for example, occurs within a single-line comment, it is |
| interpreted as a line terminator (Unicode character 000A is line feed) and |
| therefore the next character is not part of the comment. Similarly, if the |
| Unicode escape sequence \u000A occurs within a string literal in a Java |
| program, it is likewise interpreted as a line terminator, which is not |
| allowed within a string literal-one must write \n instead of \u000A to |
| cause a line feed to be part of the string value of a string literal. In |
| an ECMAScript program, a Unicode escape sequence occurring within a comment |
| is never interpreted and therefore cannot contribute to termination of the |
| comment. Similarly, a Unicode escape sequence occurring within a string literal |
| in an ECMAScript program always contributes a character to the string value of |
| the literal and is never interpreted as a line terminator or as a quote mark |
| that might terminate the string literal. |
