I don't think that's true (and I also think it never was).

You may be refering to the copy command, where you can say

   copy a.txt+b.txt+c.txt abc.txt

to concatenate the source files. But this does not restrict how you can
name your files. If you have a file a+b.txt and want to use it with copy,
then you must use double-quotes:

   copy "a+b.txt" elsewhere.txt
   copy "a+b.txt"+c.txt abc.txt
