I saw something very similar & strange happen with a software product in the
not too recent past.  We were seeing syntax errors from the command
interpreter, from a line that looked completely fine.  On a hunch, I had the
person delete what appeared to be a dash, then insert a '-' from his US
keyboard.  It worked!  Some sort of translation issue, coupled with the
origination point for the script being from a Japanese locale system.
