What is the name of this code - ?

Question

Character encoding

Actually the question has already been asked :). Tell me how to quickly determine the name of any code? Is there any service that does this?

Answer 1

The question is worded incorrectly. The code has no name. There is a name for the way to specify the code, in this case - numeric character entity reference, more precisely - numeric hexadecimal character entity reference. And there is a symbol that is represented by this code. Here, this is a character from the Unicode range reserved for private use, that is, nothing is officially assigned to this code. This range exists for icon fonts, for example where any character can be placed.
"Service for searching characters by code" is, stupidly, any search engine. Google "f88b character site:unicode.org" and you'll find what you're looking for.
