Unicode non-numeric fraction

I know you can express a lot of standard fractions using Uncode (1/2 1/4 etc)
but I thought I had seen somewhere a unicode character that was something like “A/B”

I can make it using super/sub script etc… .but it is wider than I want… any ideas? I’d like to not make a “graphic”

found them
&U2100 , &U2101 and &U214D
