C++-CLI/C# and passing unicode

I'm currently writing a program in C++ which makes use of an API in C#. I need to pass this C# package a unicode symbol (which it will then draw).

The documentation, unfortunately, doesn't account for managed code. The C# example it gives is just:

String text = "\u2197\u2300\u21A7";

But when I try to do this in the C++:

String^ convertedText= gcnew String("\u2313");

I get the error:

"Character represented by universal-character-name "\u2313" cannot be represent in the current code page (1252)"

I'm not going quite sure how to go about fixing this. Does anyone have any suggestions?

C++/CLI is still C++ so "this string" is not Unicode (which is default in C#). Just add L prefix like this:

String^ convertedText = gcnew String(L"\u2313");

Or simply:

String^ convertedText = L"\u2313";

See this article on MSDN for C++ reference and this one for C# reference. In your case these representations are equivalent to your original C# string "\u2197\u2300\u21A7:

L"\u2197\u2300\u21A7"
L"\x2197\x2300\x21A7"
L"↗⌀↧"

\u can be used to specify Unicode surrogates and modifiers, for simple characters you can use \x too.
