Yes, the hyphen versus dash issue!
When copying and pasting anything from an Office product one must be very careful as a programmer or system admin. If the text you are copying and pasting has any of these then I'd recommend DON'T DO IT.
quotes (single or double), hyphens, dashes There are probably others.
Office apps automatically change the ASCII character used for these and will cause problems in your code or as command line options as in this example.
Be very, very careful.
