User agents may use U+2010 HYPHEN <https://codepoints.net/U+2010>
when the font has the glyph, or
may use U+002D HYPHEN-MINUS <https://codepoints.net/U+002d>
otherwise. Some fonts will display slightly different glyphs for
these code points. Therefore these 2 reference files.
The M-ref.html reference file means the hyphen-Minus character U+002D.
The H-ref.html reference file means the Hyphen character U+2010.

<meta content="When 'hyphens' is set to 'manual', then words can be hyphenated only if characters inside the words explicitly define hyphenation opportunities. In this test, the characters inside the word 'Deoxyribonucleic' explicitly define 4 hyphenation opportunities. Since 9 characters can all fit inside the line box of the block box, then the word 'Deoxyribonucleic' is hyphenated only after the 3rd soft hyphen." name="assert">
