Character Sets

This appendix shows the supported character sets.

Introduction

Each character set consists of a series of control characters and displayable characters. Displayable characters are alphanumeric, symbolic or graphic characters that can be displayed on the screen or printed by a hardcopy device. Control characters enable the terminal emulation or the printer to perform specific tasks, such as a line feed or carriage return. These will be actioned when received from the host or when the emulator is in local mode and they are entered from the keyboard.

Note: When the Display Controls option in the Terminal Settings dialog box is selected, a representation of most control characters received will be displayed on the screen instead of actioned.

To enter a control character from the keyboard, first find the displayable character equivalent by adding 64 to the decimal value of the control character in the relevant character set table. For example, the control character CR (carriage return) has a decimal value of 13. Adding 64 makes 77 which is the decimal value of the displayable character M. When the Ctrl (control) key is held down and Shift + M is pressed, this will generate a CR code in local mode.

Some setup options require you to specify one or more control characters. A control character can be specified by typing ^ to represent the Ctrl key, immediately followed by the displayable character equivalent of the control character as described in the previous paragraph. For example, ^M, represents Ctrl + M, which generates the control character CR.

Another way of specifying control characters is by entering the decimal value of the ASCII character. Decimal values are entered as three-digit numbers immediately preceded by an underscore character. Values with only two digits must be preceded by a zero. For example, the decimal value of CR is 13, so this would be entered as _013.

ASCII CHARACTER SET
(Multinational 7 Bit)

The ASCII (American Standard Code for Information Interchange) character set will be selected when the language is set to North American, or the Character Set Mode option is set to Multinational. This table forms the first half of the Multinational character set, the second half of which may be the DEC Additional or one of the ISO Latin Additional sets (as determined by the Preferred Char. Set option in the Terminal Settings dialog box).

NATIONAL REPLACEMENT CHARACTERS

This table shows the characters that replace certain ASCII characters when the Character Set Mode option in the Emulation Settings dialog box is set to National. The national character set consists of the ASCII set with the changed characters listed on the line for the selected keyboard nationality.

DEC ADDITIONAL CHARACTER SET
(Multinational 8 Bit)

This is one of three possible second halves of the Multinational character set (the first half is the ASCII character set and the other possible second halves are the ISO Latin-1 and ISO Latin-2 Additional character sets). These characters may be generated when the terminal is in VT500 7 or 8 bit mode, the Character Set Mode option in the Emulation Settings dialog box is set to Multinational, and the Preferred Char. Set option in the Terminal Settings dialog box is set to DEC-MCS.

DEC LINE DRAWING CHARACTER SET

This is a special DEC character set which is used by some applications.

ISO LATIN-1 ADDITIONAL CHARACTER SET
(Multinational 8 Bit)

This is one of three possible second halves of the Multinational character set (the first half is the ASCII character set and the other possible second halves are the DEC Additional and ISO Latin-2 character sets). These characters may be generated when the terminal is in VT500 7 or 8 bit mode, the Character Set Mode option in the Emulation Settings dialog box is set to Multinational, and the Preferred Char. Set option in the Terminal Settings dialog box is set to ISO Latin-1.

ISO LATIN-2 ADDITIONAL CHARACTER SET
(Multinational 8 Bit)

This is one of three possible second halves of the Multinational character set (the first half is the ASCII character set and the other possible second halves are the DEC Additional and ISO Latin-1 character sets). These characters may be generated when the terminal is in VT500 7 or 8 bit mode, the Character Set Mode option in the Emulation Settings dialog box is set to Multinational, and the Preferred Char. Set option in the Terminal Settings dialog box is set to ISO Latin-2.

ANSI 437 CHARACTER SET

This table forms the second half of the ANSI 437 character set, the first half being the ASCII character set.

The ANSI 437 character set is used when the Preferred Char. Set option in the Terminal Settings dialog box is set to Ansi and the Ansi Code Page option is set to 437.

ANSI 850 CHARACTER SET

This table forms the second half of the ANSI 850 character set, the first half being the ASCII character set.

The ANSI 850 character set is used when the Preferred Char. Set option in the Terminal Settings dialog box is set to Ansi and the Ansi Code Page option is set to 850.

ANSI 852 CHARACTER SET

This table forms the second half of the ANSI 852 character set, the first half being the ASCII character set.

The ANSI 852 character set is used when the Preferred Char. Set option in the Terminal Settings dialog box is set to Ansi and the Ansi Code Page option is set to 852.

ANSI 858 CHARACTER SET

This table forms the second half of the ANSI 858 character set, the first half being the ASCII character set.

The ANSI 858 character set is used when the Preferred Char. Set option in the Terminal Settings dialog box is set to Ansi and the Ansi Code Page option is set to 858.

ANSI 1250 CHARACTER SET

This table forms the second half of the ANSI 1250 character set, the first half being the ASCII character set.

The ANSI 1250 character set is used when the Preferred Char. Set option in the
Terminal Settings dialog box is set to Ansi and the Ansi Code Page option is set to 1250.
