   It appears to happen with any string that fits the pattern

   .+:[^ `]*[*?\[\]].*

   I can repro this on

   Name                           Value

   SerializationVersion           1.1.0.1
   WSManStackVersion              3.0
   

   Other examples:

   /bin/echo 'a:]'
   /bin/echo "a:]"
   /bin/echo "a:["
   /bin/echo "a:*"
   /bin/echo "a:?"
   
   $string = 'a:]'
   /bin/echo $string
   /bin/echo "$string"
   /bin/echo $($string)
   /bin/echo ($string)
   /bin/echo @($string)
   
   /bin/echo 'a:llllllll]llll'
   /bin/echo 'a:lllllllllllllllll]'

   These all produce the same results.

   These all work fine though:

   /bin/echo ":]"
   /bin/echo 'a]'
   /bin/echo 'a:'
   /bin/echo 'a:a'
   /bin/echo 'aa]'
   /bin/echo 'aa]a'
   /bin/echo 'a:aa'
   Start-Process -FilePath /bin/echo -ArgumentList 'a:]'

   and

   /bin/echo 'a:`]'
   

   Prints

   a:`]
