The 2.22 documentation is obviously better here:
The name of a variable should not contain (ASCII) numbers, multiple underscores, multiple dashes or space characters. All other characters Unicode provides are allowed, for example Latin, Greek, Chinese or Cyrillic. Non-adjacent single underscores and dashes are allowed, too. In other words, variable names like HornIII or αβγXII work.
Any combination of characters is allowed if the variable name is enclosed in double quotation marks. In this case backslashes and double quotation marks need to be escaped with backslashes (not that you actually should use them). Examples: "foo bar", "a-b-c", "Horn 3".
