Bug 78923 – Update toLower and toUpper tests for Unicode 6.1 changes

• Component: JavaScriptCore
• Status: RESOLVED FIXED

[Michael Saboff]

Unicode 6.1 was release 31-Jan-2012.  It includes 5 new lower case / upper case mappings that will impact String.prototype.toLowerCase() & String.prototype.toUpperCase(). In addition, there is one mapping added in Unicode 5.2 that may not appear in tests.

The relevant changes in UnicodeData.txt are:
-- Added in 5.2 --
0265;LATIN SMALL LETTER TURNED H;Ll;0;L;;;;;N;;;A78D;;A78D
A78D;LATIN CAPITAL LETTER TURNED H;Lu;0;L;;;;;N;;;;0265;

-- Added in 6.1 --
0266;LATIN SMALL LETTER H WITH HOOK;Ll;0;L;;;;;N;LATIN SMALL LETTER H HOOK;;A7AA;;A7AA
10C7;GEORGIAN CAPITAL LETTER YN;Lu;0;L;;;;;N;;;;2D27;
10CD;GEORGIAN CAPITAL LETTER AEN;Lu;0;L;;;;;N;;;;2D2D;
2CF2;COPTIC CAPITAL LETTER BOHAIRIC KHEI;Lu;0;L;;;;;N;;;;2CF3;
2CF3;COPTIC SMALL LETTER BOHAIRIC KHEI;Ll;0;L;;;;;N;;;2CF2;;2CF2
2D27;GEORGIAN SMALL LETTER YN;Ll;0;L;;;;;N;;;10C7;;10C7
2D2D;GEORGIAN SMALL LETTER AEN;Ll;0;L;;;;;N;;;10CD;;10CD
A792;LATIN CAPITAL LETTER C WITH BAR;Lu;0;L;;;;;N;;;;A793;
A793;LATIN SMALL LETTER C WITH BAR;Ll;0;L;;;;;N;;;A792;;A792
A7AA;LATIN CAPITAL LETTER H WITH HOOK;Lu;0;L;;;;;N;;;;0266;

 JavaScript tests should be updated to test for these changes.  Given that these mappings are likely implemented in platform dependent OS code and various platforms have different adoption timelines, the tests should accept results compliant for Unicode 5 through Unicode 6.1.  For example, the existing JavaScriptCore test JavaScriptCore/tests/mozilla/ecma/String/15.5.4.11-2.js accepts either Unicode 4 or Unicode 5 results.  Maybe the 4.0 expectations can be replaced with acceptance of 5.2 and 6.1 mappings.
