Visual Studio debug 显示 utf-8 汉字

配置路径：

%VSINSTALLDIR%\Common7\Packages\Debugger\Visualizers

VS 2013

C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\Packages\Debugger\Visualizers\stl.natvis

VS2015

C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Packages\Debugger\Visualizers\stl.natvis

找到std::basic_string,将其配置下的DisplayString和StringView的值 s改为s8,
即：

<DisplayString Condition="_Myres &lt; _BUF_SIZE">{_Bx._Buf,s8}</DisplayString>
<DisplayString Condition="_Myres &gt;= _BUF_SIZE">{_Bx._Ptr,s8}</DisplayString>
<StringView Condition="_Myres &lt; _BUF_SIZE">_Bx._Buf,s8</StringView>
<StringView Condition="_Myres &gt;= _BUF_SIZE">_Bx._Ptr,s8</StringView>
