Control characters are formatting and other non-printing characters, such as ACK, BEL, CR, FF, LF, and VT. T The Unicode standard assigns code points from U+0000 to U+001F, U+007F, and from U+0080 to U+009F to control characters. 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 MfUnicodeCategory.Control category.
