Is there a Unicode character for plus over minus? (+/-)

Question

Occasionally I've seen the symbol "plus or minus" written in fractional form, like this:

Is there a Unicode character for this?

Note: I already know about the standard "plus-minus sign" symbol, but it won't work in this context. I'm specifically looking for a version with the fraction bar.

Answer 1

You can approximate it to some extent with a superscript plus (U+207A), a division slash (U+2215) and a subscript minus (U+208B):

⁺∕₋

However, it requires font support to get right. Especially the super- and subscript +/− are not available in most fonts, so it might just render horribly.

For reference, that's how it looks for me (better than five years ago, but still somewhat broken):

However, using Cambria Math in Word 2010 it looks like this:

Which probably is exactly how it should look like (follows the same typesetting rules as fractions).
