Series B and F missing ASCII Superscript Characters

[Jimmyson]

Both the Series B and F are missing 3 superscript characters to complete the 0-9 range characters.
The remaining series have the missing characters.

Unicode values need addressing:
U+00B2, U+00B3, U+00B9

Included in a rendering of each of the super/subscript character across each of the series fonts.
Note each of the font has a "1", which maps to SUPERSCRIPT LATIN SMALL LETTER I: U+2701

The good news is the glyphs are actually all there.
The bad news is they do not have the proper Unicode codes applied.
Unicode code points which do not exist in the standard are being used.
Some are marked wrong to another character.
Some are multi-mapped to the correct codes - in the ones you do see as "correct."

So the codes need to be corrected in all the fonts.
Then they will appear as expected in any character map.

OpenType Superscript and Subscript features should be added for easier access.
There are a couple other easy-to-fix issues here in the tracker.
This project appears to be dead.
Maybe I will fix these and post them in another repo.

Ahh ... I was looking at all the forks and I see you already forked and fixed the codes.
But you only fixed two of the fonts.
They all need to be fixed to get rid of the multi-mapping to non-existent codes.
And to fix the other errors (e.g. the sups 1 mapped to lowercase i).

I am not an expert with font creation, and managed to identify the issue illustrated in the picture by doing a comparison between the series glyphs...
I wouldn't know where to start with finding/identifying these issues with FontForge.
Any tips on where to start?
