Codepoints above 127 not rendering on Windows

DrawText as implemented in Raylib-cs only supports codepoints up to 127 in Windows – all characters above that gets rendered as “?”. This is kind of annoying, as I’m a swedish programming teacher, and we have a few special extended ascii-characters; å, ä and ö are part of a lit of swedish words.

Things I’ve tried:

• DrawText and DrawTextEx. Same result.
• Loading different fonts, with or without explicit inclusion of codepoints up to 255. Same result.
• Getting the latest Raylib-cs from the github page. Same result as with the nuget package.
• Running the same code but in a virtual Debian machine. THIS WORKS, so issue seems to be in Windows.
• Asking a friend who’s proficient in C/C++ to try using åäö using Raylib in C++. THIS WORKS, so the issue seems to be specific to Raylib-cs, even though it’s just a wrapper?
• DrawTextCodepoint. THIS WORKS, which means that for some reason the issue is specific to the DrawText methods (and InitWindow). Raylib is supposed to be Unicode-capable, and this proves that at least in theory, it is.

Here’s my simple test code (just writes out characters 0-255):

static void Main(string[] args)
{
  int font_size = 10;
  Raylib.InitWindow(800, font_size * 64, "åäö");
  while (!Raylib.WindowShouldClose())
  {
    Raylib.BeginDrawing();
    Raylib.ClearBackground(Color.BEIGE);
    for (int i = 0; i < 255; i++)
    {
      int col = i / 64;
      int x = col * 200;
      int y = (i % 64) * font_size;
      string text = i.ToString() + " | " + ((char)i).ToString();

      Raylib.DrawText(text, x, y, font_size, Color.BLACK);
    }
    Raylib.EndDrawing();
  }
}

It works fine in Debian, as stated, but in Windows columns 3 and 4 are filled with ?😒 and the window titlebar is also just ???.

An nice fellow on StackOverflow, who definitely deems to know more than me about these kind of things, had this to say:

The way the library imports DrawText is faulty; its default behavior “marshals” string values to fit a legacy character encoding, not necessarily UTF-8: github.com/ChrisDill/Raylib-cs/blob/… . (Specifying CharSet=Unicode probably won’t help because the DrawText function doesn’t use wide-character strings, but rather ordinary char* pointers interpreted as UTF-8.)

Thanks, @ChrisDill, can confirm both workarounds work here as well! I’ll pass the first one on to my students immediately.

Very grateful for fast & helpful response; I’ll be using this as an example in the classroom on how git/github, open source and issue tracking is supposed to work =)

I’m trying to display the pi character (π, U+03C0), but no matter what I do, all I get are underline characters. Is there any way to draw it to the screen? It seems to be at least somewhat related to this issue.

I’m using the NuGet package for Raylib-cs 3.7.0.

I believe its the same issue, I tried drawing text with a 127 unicode and it drew an underscore. I am also using Raylib-cs 3.7.0.
