Hyphen and minus sign have always been different > characters. There are some more appeareances of the hypen, which depend on the fontdesign:
1. Double horizontal stroke, fairly similar to the equal sign, but not the same. 2. Slanted single stroke, for example in Renaissance printing. 3. Double slanted stroke, as well as always used in Fraktur (blackletters). None of them can be used as a minus sign, and replacing them by a minus sign would disturb many fonts' appeareance. Gerd
