Pkg.build("StringEncodings") didn't help. Julia versions prior to Julia 1.5.0 on this machine did successfully install and use StringEncodings. Removing and reinstalling StringEncodings didn't work either.

Could you post the contents of C:\Users\JohnDoe.julia\packages\StringEncodings\B9gIH\deps\build.log? (If it doesn't exist, please run Pkg.build("StringEncodings", verbose=true).) What files exist in the C:\Users\JohnDoe.julia\packages\StringEncodings\B9gIH\deps directory?

After seeing that I removed StringEncodings, disabled my startup.jl file, and reinstalled StringEncodings without problems. My startup file does include using Dates.

plot_basic.jl:115 is the start of the documentation of a function.

I didn't look in the deps directory before reinstalling.

Probably your startup.jl file triggered a failure when running the build script. Hopefully we'll move to a more robust build system at some point.
