What means
is the upper left quarter circle. Unicode classifies it as an “other symbol” — Unicode's shelf for signs that are neither maths, money nor punctuation and files it in the Symbols for Legacy Computing Supplement block; this site shelves it under Lines & boxes.
Its appearance depends on the font and text styling.
How it is encoded
is a single code point, U+1CC35. In HTML that is , and in CSS \1CC35.
