Summary:  NSString does not handle codepoints greater than 65535

Original Submission:  Under OSX an NSString handles codepoints greater than 16 
bits

by converting them into paired surrogates - i.e. the unichars

stored in the string appear to be UTF-16. This does not work

under GNUstep.



Example - initialise a string with the UTF8 hex bytes of

0xc2, 0xa3, 0xf0, 0x90, 0x80, 0x81, 0xc2, 0xa3, 0x00

which is the encoding for three characters - 0xa3, 0x10001, 0xa3



Doing this under OSX yields a string of length '4'. Printing the 4

unichars in the string gives: 0xa3, 0xd800, 0xdc01, 0xa3 which is

the correct UTF-16 format for the string.



Under GNUstep the method stringWithUTF8String: return nil

when presented with the same daata. Taking out the over 16 bit

enccoding sequence results in the correct unichars.
