Post the font and character codes.

@Chlumsky, I know the reason. there is some problem in the font, I replace it.

[Chlumsky]

Yes, but Skia geometry preprocessing should take care of it. If this happens in a version with Skia preprocessing enabled, I would still be interested in debugging it.

@Chlumsky ,OK, I know. This is the font file.

Thanks for bringing this to my attention. I have made some improvements to geometry preprocessing and problems like these should be dramatically reduced now. If you use this font with Skia preprocessing and overlapping contours disabled (it is not needed when Skia is used), there should no longer be any artifacts.

@Chlumsky Thank you very much for so serious to the problem.

@Chlumsky，is it the Skia preprocessing ? How can I use it?

No, you just have to make sure that the CMake option MSDF_ATLAS_USE_SKIA is enabled when building msdf-atlas-gen and then it should be resolved automatically.

How should I do is? is it an option， Which is it?

[Chlumsky]

You are still using the old version. First of all, you need to build the version in master and make sure that Skia is linked. Then you just run it normally.
