A character map is a utility in most operating systems that displays the characters in a particular font. It allows users to see the full range of characters, including letters, numbers, punctuation marks, symbols, diacritical marks, and special characters that are included in a font. You can use it to copy and paste characters that you might not be able to type directly from your keyboard.
You can also find online character maps in word processing applications like Microsoft Word or Google Docs (usually found under the “Insert” menu as “Special Characters” or “Symbol“).
