Issues with Unicode Handling and Missing Primary Package Links in PackageVersions API

Hello,

I am currently using the packageversions API to retrieve package names corresponding to Git links, but I am encountering a couple of issues:

Unicode in Package Versions: When querying package names like @nio/ui-kit\u003E2.1.7\u003Ereact-dom, which includes Unicode characters (such as \u003E for >), I am not sure how to properly query these versions. Could you provide guidance on how to handle this type of input correctly?

Missing Main Package in Dependencies: When querying a Git link like https://github.com/facebook/react, I expect the package react to be included, as it is the primary package linked to this Git repository. However, when I query via the packageversions API, the main package is not included, which causes an issue. Specifically, when I attempt to use the GetDependents endpoint to retrieve the number of dependents, the count seems much smaller than expected due to the absence of the core package. Is there a way to solve this problem and retrieve the core package as well?

Any guidance or suggestions to solve these issues would be greatly appreciated.

Thank you!
