Issue: The spaces of the font "NSimsun“ don't display properly
Labels: bug,font-rendering

Type: <b>Bug</b>

I changed the font in the editor to "新宋体", then found that half corner Spaces appear the same as full corner spaces.

There are four dots in this figure indicating that there are four spaces before the printf call.

But the font is the default in Chinese in Visual Studio and the spaces display normally.
