Is there a unicode symbol for n/a? There are some fractions like ½, but an n/a symbol seems to be missing.
If there is none, what would be the most appropriate unicode symbol to use for n/a in a website (which should be contained in common fonts, to avoid needing a webfont)?
Looking at the Unicode code charts, I do not see a single N/A symbol. I do, however, see ⁿ (U+207F) and ₐ (U+2090), which you could separate with / (U+002F) eg: ⁿ/ₐ, or ̷ (U+0337), eg: ⁿ̷ₐ, or ̸ (U+0338), eg: ⁿ̸ₐ. Probably not what you are hoping for, though. And I don't know if "common" fonts implement them, either.
