I've always thought that a hyphen is a general purpose tool on a computer. It was used to seperate compound words, number ranges and a slew of other things. I was wrong.

According to this article, in UTF-8 encoding, an em or en dash are distinct. In fact, using the minus key to create a hyphen is wrong in most cases.

This one might take a little time to wrap my head around.
