.NET uses 16-bit characters, but you can use the System.Globalization.StringInfo class to iterate through a string one Unicode character at a time, index into strings by Unicode character, etc. The API's a bit awkward, but it works.

One unicode character at a time or one unicode codepoint at a time? (see character composition)

  Good point - I meant one codepoint at a time.

    But I was wrong and it's actually by grapheme, as danbruc correctly notes.

  Codepoint. Java 5 also added new string APIs for this. IIRC, Cocoa is one of the very few frameworks/languages/whatever which provides APIs for manipulating and iterating on grapheme clusters out of the box. And provides a page explaining some of the unicode concepts and how they map to NSString: https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/Strings/Articles/stringsClusters.html#//apple_ref/doc/uid/TP40008025 https://developer.apple.com/library/mac/documentation/Cocoa/...

    This is incorrect - see the definition of a text element in the remarks of http://msdn.microsoft.com/en-us/library/system.globalization.stringinfo(v=vs.110).aspx http://msdn.microsoft.com/en-us/library/system.globalization....

      Thanks for the info.

  The .NET StringInfo class provides methods to work at the grapheme level, not code points.
