||||||||||||||||||||||||||||||
Char (2 bytes): A 2-byte character field that specifies the character to be held in one character cell location of the console screen buffer. Char is the first of the <Char,Char_attributes> pair that can be repeated any number of times within the VTNT_CHAR_INFO structure. Telnet VTNT Terminal Type Format does not specify the character set to be used. Rather, client and server implementations are to be configured to use a compatible character set, such as Unicode UTF-16.<2> If the character set used is a single-byte character set such as ASCII, then the first byte of Char MUST contain the character value, and the second byte MUST be zero.
Char_Attributes (2 bytes): A 2-byte unsigned integer field that specifies an additional attribute of the character specified in the Char field immediately preceding this field. Char_attributes is the second of the <Char,Char_attributes> pair that can be repeated any number of times.
-
This field MUST be zero, or the result of a bitwise OR of one or more of the following values.
-
The values that start with COMMON MAY be used only if the character set used is a double-byte character set; those values MUST NOT be used for non-double-byte character sets.
