What Counter Clockwise Arrow is used for
In mathematical notation ↺ is an ordinary symbol: it carries no special spacing and sits in an expression the way a letter does, standing for a thing rather than doing something to the things around it. That is the classification unicode-math gives it, and it is what decides how the symbol is set: $\acwopencirclearrow$ in LaTeX, in maths mode rather than in a sentence.
Unicode publishes a second list of names for ↺ in CLDR, the keywords its own search data offers rather than the formal name, and it is anticlockwise open circle arrow. That word is what somebody looking for this character is liable to type when Counter Clockwise Arrow is not the name they know it by, and the search on the symbol lists matches it as well as the Unicode name.
How Counter Clockwise Arrow behaves in software
↺ 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.
