Hi I don't think the regex is wrong. In fact, if you change uFFFF for a smaller number, it works fine.
I have not tested each code point, mind you, but with a few tries, the highest max range that works that I could find is 0xFEFF. The range 0xFF00 - 0xFFFF apparently is reserved for control stuff. So 0xFEFF is the last value before that range. Not sure if the way the regex behaves is a bug or a feature, really, but you can probably get by with something like this: var testIsArabic:Boolean = /[\u0627-\ufeff]/.test(str.charAt(0)); Cheers Juan Pablo Califano 2009/10/19 Matt Muller <matthewmul...@gmail.com> > Hi there, > > issue with regex when trying to test if a char is within a unicode range > > var testIsArabic:Boolean = /\u0627/.test(str.charAt(0)); // this works > testing for arabic chars of unicode 0627 > > var testIsArabic:Boolean = /[\u0627-\uFFFF]/.test(str.charAt(0)); //// this > range does not work, returns false > > NOTE: the str.charAt(0) is 0627 > > any ideas? > > cheers, > > MaTT > _______________________________________________ > Flashcoders mailing list > Flashcoders@chattyfig.figleaf.com > http://chattyfig.figleaf.com/mailman/listinfo/flashcoders > _______________________________________________ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
