Kotoistus - Minus

Unicode has several hyphen/dash/minus characters.
Here is their current availability under X with the Finnish keyboard layout:

* if XK_PUBLISHING is defined, the alias points to this value.
** Produced by multikey combination.
*** Finnish is the only language where anything other than minus and hyphen are found.

In other words, we can produce the HYPHEN-MINUS, SOFT HYPHEN, EN DASH and EM DASH
characters. In other languages, only HYPHEN-MINUS and SOFT HYPHEN can be produced.



We can add these other characters to the available repertoire, as long as
no confusion is created by doing so.
