Debugging into NuGet symbol package source folder with spaces fails

[vdehaven]

Using Klondike 2.1.1, we internally host NuGet packages with their symbol packages. Our source package in question has the following structure:

src\
    Project1\
        Classes\
            With Space\
    Project2\
        Classes\
            Another Space\

Using Visual Studio 2015 Update 3, the debugger is able to step into any class in either of the Classes folders. If any code in either of the *Space folders is stepped into, the Find Source dialog is displayed, and no code appears in the symbol cache.

Unzipping a folder with spaces will encode them as %20. However, NuGet does not. Is unzipping possibly happening?

I'm not sure where the origin of the issue lies, so this was also posted on StackOverflow.
