@AlexTalker, нет, не значит=) Там все очень ограниченно. en.cppreference.com/w/cpp/io/c/fscanf. В частности, "[set]
matches a non-empty sequence of character from set of characters.
If the first character of the set is ^, then all characters not in the set are matched. If the set begins with ] or ^] then the ] character is also included into the set."
