Other math symbols
₃ lives in the Superscripts and Subscripts block (U+2070-U+209F), raised and lowered digits and letters. Within Unicode it is classified as No, a number that is not a digit. Fractions and superscript digits sit here. Its bidirectional class makes it a European number.
What happens to ₃ in a search box
₃ is a subscript form: Unicode says it can be rewritten as 3, one character. Anything that normalises text to NFKC before comparing it does exactly that, which is why ₃ pasted into a search field, a URL slug or a username can come back as 3 and match text that never contained ₃ at all. NFC, the form this site uses, leaves it alone. Unicode also records its numeric value as 3, so software that asks a character what number it is gets 3 rather than an error.
How Subscript Three behaves in software
₃ is East Asian Ambiguous: one column in a Western locale and two in a CJK one. That is why a table that lines up on your machine can break on somebody else's, with no change to the text at all.
