| 9 ECMA Section: Source Text | |
| 10 Description: | |
| 11 | |
| 12 ECMAScript source text is represented as a sequence of characters | |
| 13 representable using the Unicode version 2.0 character encoding. | |
| 14 | |
| 15 SourceCharacter :: | |
| 16 any Unicode character | |
| 17 | |
| 18 However, it is possible to represent every ECMAScript program using | |
| 19 only ASCII characters (which are equivalent to the first 128 Unicode | |
| 20 characters). Non-ASCII Unicode characters may appear only within comments | |
| 21 and string literals. In string literals, any Unicode character may also be | |
| 22 expressed as a Unicode escape sequence consisting of six ASCII characters, | |
| 23 namely \u plus four hexadecimal digits. Within a comment, such an escape | |
| 24 sequence is effectively ignored as part of the comment. Within a string | |
| 25 literal, the Unicode escape sequence contributes one character to the string | |
| 26 value of the literal. | |
| 27 | |
| 28 Note that ECMAScript differs from the Java programming language in the | |
| 29 behavior of Unicode escape sequences. In a Java program, if the Unicode escape | |
| 30 sequence \u000A, for example, occurs within a single-line comment, it is | |
| 31 interpreted as a line terminator (Unicode character 000A is line feed) and | |
| 32 therefore the next character is not part of the comment. Similarly, if the | |
| 33 Unicode escape sequence \u000A occurs within a string literal in a Java | |
| 34 program, it is likewise interpreted as a line terminator, which is not | |
| 35 allowed within a string literal-one must write \n instead of \u000A to | |
| 36 cause a line feed to be part of the string value of a string literal. In | |
| 37 an ECMAScript program, a Unicode escape sequence occurring within a comment | |
| 38 is never interpreted and therefore cannot contribute to termination of the | |
| 39 comment. Similarly, a Unicode escape sequence occurring within a string literal | |
| 40 in an ECMAScript program always contributes a character to the string value of | |
| 41 the literal and is never interpreted as a line terminator or as a quote mark | |
| 42 that might terminate the string literal. | |
