PowerShell: best way to escape double quotes in string passed to an external program? E.g., a JSON string

Question

I read I think all the articles on escaping strings in PowerShell, but I still haven\'t found the solution that would satisfy me.

Suppose I have a file foo.jso

Answer 1

Unfortunately, PowerShell's passing of arguments with embedded double quotes to external programs is broken, requiring you to manually \-escape them as \":

myprogram ((Get-Content -Raw ~/foo.json) -replace '"', '\"')

^{Note the use of Get-Content -Raw, which is preferable to Get-Content ... | Out-String for reading the entire file into a single, multi-line string, but note that it requires PSv3+.}
