Missing glyphs: ↊ and ↋ for dozenal

[rolfmeles]

Missing turned digits 2 and 3 (↊ and ↋)

When using the dozenal system, you would count 1, 2, … 9, ↊, ↋, 10
Some people use a and b or other glyphs. But the dozenal society of Great Britain suggests ↊ and ↋ and they have unicode slots: U+218A (↊)
and
U+218B (↋).

To include them, all that needs to be done, is to put a copy of 2 or 3 in the unicode slots and turn them 180°.

Would make this font much more complete for me!

Should I post this issue in source-sans too?

Interesting – thanks for explaining these code points!
Would you have examples for other fonts including these glyphs? The only one I find on my machine is Everson Mono …
Real-world use examples are also welcome.

If you are interested in having these glyphs included in Source Sans/Source Code, please post an issue there as well. This issue can link back to here.

This is in deed a problem, most Fonts I have don't include these. That's why I often add them myself if I like a font. I even edited my computers keyboard layout in order to type them easily.
The glyphs are only there for the dozenal system so you don't have to use letters. The number 1↊7↋ looks much more like a number than 1a7b. They are called the Pitman digits, as Isaac Pitman suggested them. More about the dozenal system on wikipedia: https://en.wikipedia.org/wiki/Duodecimal
