May en-dashes be used in sports scores?
Solution 1:
It does look rather awkward to me, but there's nothing wrong with it. An en dash is typically used for ranges, but it can also be used for relationships and connections as in sports scores and votes, though these usages are somewhat contested, or just plain falling out of favour.
Typographywise, I think I would prefer to use a figure dash if it's available. It usually isn't, though, and in most fonts, the en dash is actually a better substitute for the figure dash than the hyphen is, so you should just use whatever works, I guess.
