Could not list NuGet packages in Visual Studio 2017 when using Artifactory Nuget source

I have successfully published a Nuget package to Artifactory Nuget repository, but I got some problems as below:

1. The package doesn't show up in Visual Studio 2017 Nuget Package Manager
2. The Artifactoy doesn't display Nuget Package properties in Artifactory UI

I believe that nuspec file of the Nuget package cannot contain Chinese characters because once I remove Chinese characters everything is back to normal.

If I want to keep nuspec file contain Chinese characters, is there any way that Artifactory and VS 2017 could work fine?
