Original Pull Request: https://github.com/microsoft/terminal/pull/17710

State: closed
Merged: Yes

HSTRING does not permit strings that aren't null-terminated.
As such we'll simply use a plain char array which compiles down to
a UINT32 and wchar_t* pointer pair. Unfortunately, cppwinrt uses
char16_t in place of wchar_t, and also offers no trivial conversion
between winrt::array_view and std::wstring_view either.
As such, most of this PR is about explicit type casting.

Closes #17697

Validation Steps Performed

  • Patch the DeviceAttributes implementation in adaptDispatch.cpp
    to respond like this: 
    _api.ReturnResponse({L"ABCD", 3});
  • Open a WSL shell and execute this: 
    printf "\e[c"; read
  • Doesn't crash ✅
