I can type ⅓, ⅔ and ½ but can I type 3/3 and 2/2 using unicode? I know that from a mathematical point of view the fractions 2/2 = 3/3 = 1 but I am typing a list where I want to indicate that you have reached the final step (third step out of three steps) and entering "1", after ⅓ and ⅔, would confuse most readers, including myself if I look at my own list some time after I wrote it.
The "target" environment where I want to write these characters are unicode-aware text editors, some that support "rich formatting" and other typographic features.
(I was very hesitant regarding which forum this question would be on topic in so bear with me if you think I should have posted in somewhere else. The area I use this in is source code, hence UX and graphic design seemed off topic.)
Update: here are some screenshots of how superscript - fraction slash - subscript looks in TextEdit in OS X. Font is Helvetica. In the first image the font size is 12 pt, in the second 48 pt. As you can see the spacing is quite off and the subscript character looks quite odd, especially in the second image where it looks like to different character weights.
