OverStrike control character

[abrahamgross at disroot.org]

If epigraphers and numismaticians have the need for overstiking in plain text, isn't that reason enough to encode it? Unicode encoded many completely extinct scripts* and extinct characters in existing scripts, so adding the overstrike doesn't seem like a stretch at all.

Does Yeoman show the “8 over 7” visually too, or does it just say “8 over 7” and you're supposed to imagine it urself?

*Extinct scripts in Unicode:
Georgian capitals
Ogham
Runes
Glagolitic
Linear B
Phaistos disc
Lycian
Carien
Old (RTL) Italic
Gothic
Old Permic
Cuneiform
Deseret (conscript)
Shavian (conscript)
Linear A
Cypriot
Imperial Aramaic
Palmyrene
Nabatean
Hatran
Phoenician
Lydian
Meroitic
Old South Arabian
Old North Arabian
Avestan
Inscriptional Parthian
Inscriptional Pahlavi
Psalter Pahlavi
Old Turkic
Old Hungarian
Brahmi

Then there are many extinct scripts in the propsal stage like oracle bone and classical yi
