506052 - Case insensitive Regular Expression match doesn't work for non-latin characters

Status: RESOLVED WONTFIX

(Tamarin Graveyard :: Virtual Machine, defect)

Description

[Chris Peyer]

Attachment: js sample of issue

Steps to reproduce: 

Try the following: 
trace("Č".match(/č/i)); 
trace("Ą".match(/ą/i)); 
trace("Ä".match(/ä/i)); 
trace("Å".match(/å/i)); 

 Actual Results: 
 All of the above return null. 
  
 Expected Results: 
 They should return matches (1-element arrays) just like the following returns ["A"]: 
  "A".match(/a/i)) 
 The same problem applies to replace. 

 Workaround (if any): 
 You can use toUpperCase for both strings: 

 s1.toUpperCase().match(new RegExp(s2.toUpperCase(), "")) 
  
 the problem is however that the returned result will differ from the original (will by upper-case). 

Interestingly, even toUpperCase() doesn't work at all for "å". Maybe it shouldn't - I don't know Finnish language and the rules that apply to it.

All of the above (including å) work fine in JavaScript (tested with Firefox and IE).

Also getting null w/ spidermonkey. Not sure of what proper behaviour should be.

The attached file is a test for both issues this one and http://bugs.adobe.com/jira/browse/ASC-3253 

It returns expected results in all three major browsers (FF, Opera, IE).
