Since SARA U is a non-spacing mark, we don't allow partial matching.

Trying to cause partial matching, even for Thai/Indic/Hebrew/Arabic  
scripts that some of non-spacing marks are vowels, is considered a  
good UI since it's harder for users to determine the paritiel  
selection within a graphic element.


If you really need to do the partial matching, specifying  
NSLiteralSearch flag allows it.


Thanks a lot! With NSLiteralSearch everything works perfectly now.

Kind regards,

Gerriet.

I tried this:

if ( ra.location == NSNotFound )

Re: Find with Nonspacing_Mark

2008-12-29 Thread Aki Inoue 
Actually Thai vowels are not considered a diacritics and, thus, not  
ignored by the flag.


Also, note that, even though it is true we sometimes take advantage of  
ICU from our frameworks, it is an implementation detail and should not  
be considered always true.


In this particular case, we're not using ICU :-)

If you think that there's something wrong with this particular case,
you can file a bug against Cocoa, but you might also want to file one
against ICU, .  It's the ICU tables that
determine string equality in Cocoa.
