Guidance on output redirection for Windows

[DanielRosenwasser]

If I try running the trace analyzer with npx analyze-trace --color false > foo.txt, then foo.txt gets something like the following output.

instead of the expected box drawing characters

This is apparently because Node.js outputs to UTF8, and PowerShell's redirection functionality (at least the version I'm using, 5.1) thinks it's receiving UTF16. The fix is to set

[Console]::OutputEncoding = [System.Text.UTF8Encoding]::new()
