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