How can I display a squared sign in unicode (I checked the Unicode reference and it is not there)?
Also, is it possible to use unicode to display a fraction, for example 3/4 would look as it should with the horizontal vinculum?

For the fraction, you need the combining fraction slash (U+2044): “ ⁄ ”, but you have no guarantee that the client will render it in the same way vulgar fractions such as ¼.
For the squared sign “²”, you’ll find it at U+00B2, near all the other superscript digits, and just before the subscript digits.
