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. 58 59 Author: christine (at) netscape.com 60 Date: 12 november 1997 61 */ 62 63 var SECTION = "6-1"; 64 var VERSION = "ECMA_1"; 65 startTest(); 66 var TITLE = "Source Text"; 67 68 writeHeaderToLog( SECTION + " "+ TITLE); 69 70 var testcases = new Array(); 71 72 testcases[tc] = new TestCase( SECTION, 73 "// the following character should not be interpreted as a line terminator in a comment: \u000A", 74 'PASSED', 75 "PASSED" ); 76 77 // \u000A testcases[tc].actual = "FAILED!"; 78 79 tc++; 80 81 testcases[tc] = new TestCase( SECTION, 82 "// the following character should not be interpreted as a line terminator in a comment: \\n 'FAILED'", 83 'PASSED', 84 'PASSED' ); 85 86 // the following character should noy be interpreted as a line terminator: \\n testcases[tc].actual = "FAILED" 87 88 tc++; 89 90 testcases[tc] = new TestCase( SECTION, 91 "// the following character should not be interpreted as a line terminator in a comment: \\u000A 'FAILED'", 92 'PASSED', 93 'PASSED' ) 94 95 // the following character should not be interpreted as a line terminator: \u000A testcases[tc].actual = "FAILED" 96 97 testcases[tc++] = new TestCase( SECTION, 98 "// the following character should not be interpreted as a line terminator in a comment: \n 'PASSED'", 99 'PASSED', 100 'PASSED' ) 101 // the following character should not be interpreted as a line terminator: \n testcases[tc].actual = 'FAILED' 102 103 testcases[tc] = new TestCase( SECTION, 104 "// the following character should not be interpreted as a line terminator in a comment: u000D", 105 'PASSED', 106 'PASSED' ) 107 108 // the following character should not be interpreted as a line terminator: \u000D testcases[tc].actual = "FAILED" 109 110 test(); 111 112 function test() { 113 for ( tc=0; tc < testcases.length; tc++ ) { 114 testcases[tc].passed = writeTestCaseResult( 115 testcases[tc].expect, 116 testcases[tc].actual, 117 testcases[tc].description +" = "+ 118 testcases[tc].actual ); 119 120 testcases[tc].reason += ( testcases[tc].passed ) ?
