In computer science, an illegal character is a character that is not allowed by a certain programming language, protocol, or program. [1] To avoid illegal characters, some languages may use an escape character which is a backslash followed by another character. [2]
In the Windows operating system, illegal characters in file and folder names include colons, brackets, question marks, [3] and null characters. [4]
