This information, of course, pre-supposes that you are using a font that
is at least partly Unicode compliant; many aren't.

Character decimal 173 (hex 00AD) is not the en-dash but the Latin-1 alphabet and Unicode character SOFT HYPHEN. This is the same character that OpenOffice produces by simultaneous pressing of CTRL and the hyphen key.

En-dash is Unicode 2013.

2010 HYPHEN. (A hyphen clearly distinguished from the ASCII HYPHEN-MINUS which generally does double duty for hyphen and minus sign. In fact most people, even when generating Unicode, use the ASCII HYPHEN-MINUS, especially since this character is blank in most fonts.

2011 NON-BREAKING HYPHEN. (Should perform as does OpenOffice CTRL-SHIFT-HYPHEN. Missing from most fonts.)

2012 FIGURE DASH. (Missing from most fonts.)

2013 EN DASH

2014 EM DASH

2015 HORIZONTAL BAR (= QUOTATION DASH).
