A new “Fraction Slash and Fonts” thread in the BÉPO community has brought up
that this works mainly with new and ambitious fonts:
• Carlito
• Fira Sans
• Linux Biolinum
• Linux Libertine
• Roboto
• Source Sans Pro
• Source Serif Pro
• Ubuntu

By contrast, the typefaces not supporting U+2044 correctly include:
- FreeSans
- FreeSerif
- Open Sans
- DejàVu
- Droid
- Liberation
- TeX Gyre

BTW, the Times New Roman font that the Mailing List Archives specify, belongs to
this latter category, so that the fractions with U+2044 and normal size digits
display in fallback mode.

Software support is mainly found in open projects as we have seen:
• HarfBuzz, and its users:
• LibreOffice
• Firefox
• Chrome

In the meantime, Microsoft products not supporting U+2044 correctly include:
- DirectWrite
- Internet Explorer including its last version 11

➔ Does anybody know why Microsoft is reluctant in supporting U+2044?

➔ And why on the other hand, the widespread and popular way of writing fractions
   as <superscript>U+2044<subscript> sequences is discouraged and even ridiculized?
