In C#, the native string representation is actually determined by the Common Language Runtime. In CLR, the string data type is a sequence of char, and the char data type represents a UTF-16 code unit. The native string representation is essentially UTF-16, except that strings can contain sequences of UTF-16 code units that aren't valid in UTF-16 if the string contains incorrectly-used high and low surrogates.
C# string literals support the \u escape sequence for 4-digit hexadecimal Unicode code points, \U for 6-digit code points, and UTF-encoded source code is also supported so that "Unicode strings" can be included in the source code as-is.
C# benefits from the extensive support for Unicode in the .NET Base Class Library, including
* Various UTF encodings
* String normalization
* Unicode character database subset
* Breaking strings into text elements
