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@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 // encoded quotes should not end a quote 73 74 testcases[tc++]= new TestCase( SECTION, 75 "var s = 'PAS\\u0022SED'; s", 76 "PAS\"SED", 77 eval("var s = 'PAS\\u0022SED'; s") ); 78 79 testcases[tc++]= new TestCase( SECTION, 80 'var s = "PAS\\u0022SED"; s', 81 "PAS\"SED", 82 eval('var s = "PAS\\u0022SED"; s') ); 83 84 85 testcases[tc++]= new TestCase( SECTION, 86 "var s = 'PAS\\u0027SED'; s", 87 "PAS\'SED", 88 eval("var s = 'PAS\\u0027SED'; s") ); 89 90 91 testcases[tc++]= new TestCase( SECTION, 92 'var s = "PAS\\u0027SED"; s', 93 "PAS\'SED", 94 eval('var s = "PAS\\u0027SED"; s') ); 95 96 testcases[tc] = new TestCase( SECTION, 97 'var s="PAS\\u0027SED"; s', 98 "PAS\'SED", 99 "" ) 100 var s = "PAS\u0027SED"; 101 102 testcases[tc].actual = s; 103 104 tc++; 105 106 testcases[tc]= new TestCase( SECTION, 107 'var s = "PAS\\u0027SED"; s', 108 "PAS\"SED", 109 "" ); 110 var s = "PAS\u0022SED"; 111 112 testcases[tc].actual = s; 113 114 115 test(); 116 117function test() { 118 for ( tc=0; tc < testcases.length; tc++ ) { 119 testcases[tc].passed = writeTestCaseResult( 120 testcases[tc].expect, 121 testcases[tc].actual, 122 testcases[tc].description +" = "+ 123 testcases[tc].actual ); 124 125 testcases[tc].reason += ( testcases[tc].passed ) ?
