Use ASCII HYPHEN-MINUS when there's no HYPHEN in the font.

Previously, we just assumed the font in use had a U+2010 HYPHEN
character, resulting in a tofu (or an empty space) being shown when
U+2010 was not supported in the font used to render the hyphenated
word.

Now we try to fallback to U+002D HYPHEN-MINUS, which has a very good
chance of being available in at least any Latin font.

We still show a tofu when neither character is supported, to
intentionally alert that something is missing.
