Other fractions symbols
One Third is not the only name it goes by: people look for ⅓ as 1/3 too, and the search box on this site matches that as readily as the Unicode name.
⅓ 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 ⅓ in a search box
⅓ is a precomposed fraction: Unicode says it can be rewritten as 1⁄3, three separate characters. Anything that normalises text to NFKC before comparing it does exactly that, which is why ⅓ pasted into a search field, a URL slug or a username can come back as 1⁄3 and match text that never contained ⅓ at all. NFC, the form this site uses, leaves it alone. Unicode also records its numeric value as 0.3333333333333333, so software that asks a character what number it is gets 0.3333333333333333 rather than an error.
How to type ⅓ on Windows
On Windows, the Alt code for ⅓ is above 255, so Windows will not take it as typed. Press Win + . and use the symbols tab, or copy it from this page.
How One Third behaves in software
⅓ 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. 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.

If ⅓ arrives as â…“
One character has become three, which is what a three-byte UTF-8 sequence looks like when each byte is read separately: E2 85 93 read as Windows-1252 gives exactly â…“. The text is intact and the damage is in the reading, so setting the reader to UTF-8 restores it and retyping does not. A rectangle instead of the mojibake means the opposite: the encoding is right and the font has no glyph at U+2153, which for a character this far outside Latin-1 is common in older office fonts.
