It is probably worth noting that the first Arabic character in the above filename (i.e. the one that appears on the right, adjacent to the period) has a canonical decomposition, as per this line from UnicodeData.txt (http://www.unicode.org/Public/9.0.0/ucd/UnicodeData.txt <http://www.unicode.org/Public/9.0.0/ucd/UnicodeData.txt>): 0625;ARABIC LETTER ALEF WITH HAMZA BELOW;Lo;0;AL;0627 0655;... That is, in some cases this character 0625 (UTF8: D8 A5) will be converted to the sequence 0627 0655 (UTF8: D8 A7 D9 95). This decomposition was introduced in Unicode 3.0. If there are processes that use decomposition according to Unicode 9 versus Unicode 2.x, or processes that don't decompose versus ones that do, then the filename bytes will be different. - Peter E _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
