Other fractions symbols
⅘ lives in the Number Forms block (U+2150-U+218F), fractions and Roman numerals as single characters. Within Unicode it is classified as No, a number that is not a digit. Fractions and superscript digits sit here.
What happens to ⅘ in a search box
⅘ is a precomposed fraction: Unicode says it can be rewritten as 4⁄5, three separate characters. Anything that normalises text to NFKC before comparing it does exactly that, which is why ⅘ pasted into a search field, a URL slug or a username can come back as 4⁄5 and match text that never contained ⅘ at all. NFC, the form this site uses, leaves it alone. Unicode also records its numeric value as 0.8, so software that asks a character what number it is gets 0.8 rather than an error.
How Four Fifths behaves in software
⅘ takes one column in a terminal. It carries no direction of its own, so in a line that mixes English with Arabic or Hebrew it takes the direction of the text around it rather than forcing one.
