Control characters are non-printing and formatting characters, such as ACK, BEL, CR, FF, LF, and VT. The Unicode standard assigns the following UTF-16 code units to control characters: from \U0000 to \U001F, \U007F, and from \U0080 to \U009F. According to the Unicode standard, these values are to be interpreted as control characters unless their use is otherwise defined by an application. Valid control characters are members of the UnicodeCategory.Control category.
