What is .Net Unicode Encoding's equivalent in Objective-C?

Question

What is the equivalent in Objective-C of .Net's System.Text.Encoding.Unicode? I have tried:

• NSUnicodeStringEncoding
• NSUTF8StringEncoding
• NSUTF16StringEncoding

None of the above converted the text back correctly.

According to http://msdn.microsoft.com/de-de/library/system.text.encoding.unicode.aspx, System.Text.Encoding.Unicode is the little-endian UTF-16 encoding. The equivalent NSString encoding is NSUTF16LittleEndianStringEncoding.

NSUTF16StringEncoding is almost the same, but prepends a Unicode Byte-Order Marker (BOM) FF FE to the data. (And strictly speaking, it is not documented that NSUTF16StringEncoding uses little-endian, so the explicit NSUTF16LittleEndianStringEncoding should be used anyway.)
