Can't load codepoints needed for Unicode text rendering

As far as I've looked, if you want to use text with foreign characters you need to specify codepoints --the conversion codes from UTF-x to real Unicode-- in the Font object. The examples I've looked include iterating for a specific range of characters to match the language you want (for C Raylib).

int codepoints[512] = { 0 };
for (int i = 0; i < 95; i++) codepoints[i] = 32 + i;
for (int i = 0; i < 255; i++) codepoints[96 + i] = 0x400 + i;
Font font = LoadFontEx("arial.ttf", 32, codepoints, 512);

I've tried something similar in a project:

 // codepoints
  std::vector<int> codepoints;
  // Load codepoints from a Unicode subset (Basic Latin)
  for (int cp = 0x20; cp <= 0x7E; ++cp)
    codepoints.push_back(cp);

  raylib::Font font{"src/Milonga-Regular.ttf", 30, codepoints.data(),
                    static_cast<int>(codepoints.size())};

  raylib::Text text{text_str, 30, WHITE, font};

  (...)
  while (!w.ShouldClose()) // Detect window close button or ESC key
  {
    // Update
    // TODO: Update your variables here
	(...)

    // Draw
    BeginDrawing();
    ClearBackground(GetColor(gunmetalGray));

	(...)
    text.Draw(Vector2{20, 20});

    EndDrawing();
  }

...but it doesn't work.

Another solution in Raylib is using GetCodepoints() for a string, but there's no bindings for that.
There's a recommended approach for raylib-cpp or...?

Start by reviewing the raylib-cpp Font usage shown in the issue and the raylib GetCodepoints() API it references. Determine how Unicode text and codepoints should be exposed through the wrapper, then verify that the recommended approach works for the reported rendering case.
