aws-cdk: CDK for .NET cannot handle Swedish characters in TEMP/TMP path

CDK for .NET Core does not seem to be able to handle paths with non-ascii characters in them. My username in Windows is having an å character, which seems to cause an issue becuase the TEMP folder contains that letter in it’s path.

Reproduction Steps

SET TMP to c:\path_with_å_in_it
Run cdk synthesize, where you have a csharp project (or any cdk command it seems)

Error Log

An exception is thrown:

Unhandled exception. Amazon.JSII.Runtime.JsiiException: ENOENT: no such file or directory, stat 'C:\Users\PerG´┐¢rdebrink\AppData\Local\Temp\x0c4glzt.kiq\Amazon.CDK.CloudAssembly.Schema.aws-cdk-cloud-assembly-schema-1.33.1.tgz'

fix(dotnet): crash when TEMP contains certain unicode characters (#1913) In certain environments, the temporary directory path may contain unicode characters. If those are not properly encoded as UT... — committed to aws/jsii by RomainMuller 4 years ago

When looking at this again, I wonder if its a JSII + Windows issue and not specific to those characters. @RomainMuller does this look familiar relating to recent windows fixes in JSII?

I suspect that it’s some kind of encoding/decoding issue and that the problem is generally related to non-ascii characters?

Btw, I see that the exception I wrote in the issue was when the TMP was set to my windows profile folder name. If you set TMP to the path in the step above, the exception message would of course be something like Unhandled exception. Amazon.JSII.Runtime.JsiiException: ENOENT: no such file or directory, stat 'C:\path_with_´┐¢in_it\x0c4glzt.kiq\Amazon.CDK.CloudAssembly.Schema.aws-cdk-cloud-assembly-schema-1.33.1.tgz'

Let me know if you need more information to reproduce the issue or if you want me to provide more information
