In NSString APIs all references to "characters" is UTF-16, in native endianness.

Hmmm!! I'm going to have to go back and check on this, but I'm sure I tried it.
But I'll go back and look anyway.



So initWithCharacters:... and getCharacters: should have worked for you, at least for big endian data on the PowerPC.

Will try it again - just to be sure, but I'm almost for certain I tried it last week with this
assumption.



However, if the characters are not native endianness, it's best to use one of the encoding methods joar points out.

I have utilities to convert back and forth for buffers of 16 bit (words). But once I get
data into the Mac, it's all treated as Big Endian.


I'm surprised that Apple waited until just now to support this..... because none of the encodings
Apple supports seems to indicate any 16 bit character encodings, unless they named it
differently. In the Docs, most indicate 8 or 7 bit characters, but 2 or 3 -


NSUnicodeStringEncoding
NSWindowsCP1250StringEncoding
 <and a number of other winBlows encodings>

Don't seem to explicitly say the character sizes are 16 bits.

Knowing nothing about WinBlows, I hardly can be expected to know this. Can I assume that since they don't explicitly specify the character sizes of 8 or 7 bits
that they are assumed to be 16 bits?
