It is possible to search for superscript and subscript digits in fractions? [solved]

The correct way to put the fraction one 48th in Numista is the digit one, followed by a fraction slash, followed by 48 (1⁄48). I've found many pages where Unicode superscript and subscript digits are used instead (¹⁄₄₈). This doesn't look as good.

Is there a way to search these instances? (Automatic fix would be nice, depending on the number of entries.)

I tried searching for *¹* but it returned the same results as *1*.

Hello,

There is now an automatic correction in place that will replace the wrongly formatted fractions in coin and banknote titles.
641 titles have been fixed with the initial run. See for example N#67 , which was previously called “¹⁄₂₆ Shilling - Victoria” and is now called “1⁄26 Shilling - Victoria”
