--- Comment #4 from Heiko Tietze <heiko.tietze at documentfoundation.org> ---
In contrast or supplementary to the hyphen minus U+002D, the glyph U+2212 is
the minus sign, see https://www.compart.com/en/unicode/U+2212.

I support this request, although it was rejected previously (in a wider
context). 

(In reply to Eike Rathke from bug 125068 comment 8)

+1 (cutting off the "Not much desirable for me." because not working
everywhere)
