PSGraph in Azure Pipelines

[LxLeChat]

Hi, First thanks for you work! great module!

I'm running a build in AZPipelines, and running some tests.
I'm getting this types of error when using PSGraph in pester scripts ( works fine on local machines )

Error: <stdin>: syntax error in line 1 near 'digraph'
    [-] Parameter: -Path (file): Should return Object of type [FileInfo] 1.08s
      ParseException: System error.
      at Export-PSGraph<End>, C:\Users\VssAdministrator\Documents\WindowsPowerShell\Modules\psgraph\2.1.38.27\PSGraph.psm1: line 907

[-] Parameter: -Path (file): Should Create a graph in same folder 108ms
      RemoteException: Error: <stdin>: syntax error in line 1 near 'digraph'
      at Export-PSGraph<End>, C:\Users\VssAdministrator\Documents\WindowsPowerShell\Modules\psgraph\2.1.38.27\PSGraph.psm1: line 904

I added the image because of the strange caracter begfore digraph ... :(

@LxLeChat I usually suspect encoding (possible BOM) when I see a character like that. digigraph is the first keyword at the start of the text stream.

Looking at the code around this, I am calling the graphviz engine directly and it is having an issue with the file. I suspect that if you called the dot.exe with that same file path that it would give you that second error message about the syntax error.

$null = & $graphViz @($arguments + $file.path)
