Some characters in the Latin Extended-F block are superscripts of some characters in the Latin Extended-G block, so the latter block could also be done afterwards.
I mean, for example, two zeros three ones (00111) -> 023 (the reason for the leading 0 is that the un-truncated number starts with 0, and if the number starts in 1, the truncated version doesn't need any leading number).
Thanks for the comment! Unfortunately, the design of these glyphs you mentioned, is actually based on another font named NexaHelv 9 Medium. So, there you go!
