Sure thing! The command I was trying to send through looked like this:

pushover -m "($runcount/$totalcount) Encode completed!"$'\n'"$i"$'\n'"Elapsed: $runtime"

$runcount is numerical (i.e. "9")
$totalcount is numerical (i.e. "40")
$i is a filename string (i.e. "The Matrix (1999).mkv")
$runtime is a calculated elapsed time string (i.e. "1h 37m 22s")

It failed every single time until I moved the leading parenthesis and ONLY started the pushover message with an alphanumeric character (0-9,a-z, A-Z).

Once I figured out it was barfing on the parenthesis, I reworded to include the $runcount and $totalcount AFTER some text, but still enclosed in parentheses - No issues whatsoever.

Oh. I should also mention that I tried a few ways to escape the parenthesis as well...all failed.
