[QuellaZhang]

Environment: Windows Server 2016 + VS2019 + EASTL master branch latest d996510 source code.

EASTL failed to build due to error C2664: 'void (const char8_t *)': cannot convert argument 1 from 'const char [51]' to 'const char8_t *'. Could you help have a look about this issue? Thanks in advance!

repro step:

1. git clone https://github.com/electronicarts/EASTL F:\EASTL\src
2. Open a VS 2019 x86 command prompt as admin and browse to F:\EASTL\src
3. git submodule update --init
4. mkdir build_x64 && pushd build_x64
5. set CL=/std:c++latest
6. cmake -G "Visual Studio 16 2019" -A x64 -DCMAKE_SYSTEM_VERSION=10.0.18362.0 -DEASTL_BUILD_TESTS:BOOL=ON -DEASTL_BUILD_BENCHMARK:BOOL=OFF ..
7. msbuild /m /p:Platform=x64 /p:Configuration=Release EASTL.sln /t:Rebuild
