This is why the use of explicitly coded subscript and superscript digits for vulgar fractions is not recommended. Rather, one needs to hope that the font one is using supports U+2044 FRACTION SLASH. As not all fonts support all superscript and subscript digits, text using them may render badly, whereas U+2044 itself will usually be rendered at least tolerably even if the glyph comes from a different font to the digits. The truly straight Unicode approach in HTML is to use 19⁄45. Just entering those 5 characters into a text entry box in Firefox gave me a properly formatted vulgar fraction. That is how vulgar fractions are supposed to work. Unfortunately, one may need to avoid 'exciting new fonts' in favour of those with a large, working repertoire. Richard.
