14.11 Unicode in E1012 and E1022
Unicode is a global standard for character encoding where 16-bit values are used to
represent the characters from many of the world’s languages. Previous standards for
character encoding, such as the Microsoft Windows ANSI character set, use 8-bit
character values or combinations of 8-bit values to represent the characters used in a
certain language or geographical region.
In Microsoft Windows 2000 and Windows XP, IMEs (Input Method Editors) are
used to permit the computer user to write in complex characters and symbols, such
as those used Chinese, with a standard keyboard. The character sets installed in the
computer are used. IMEs for various languages are added under Control Panel/Key-
board/ Input language. When new character sets are installed, all necessary charac-
ters are added to the system.
The configuration tool uses a Unicode charcter set to display Unicode characters in
the computer’s dialog boxes. Only those Unicode characters that are used in the
project will be downloaded to the operator panel during the project transfer.
Terminal Font
A character set is used in the operator panel to display Unicode characters. The char-
acter set in the panel contains approximately 35,000 characters but is not complete
according to the Unicode standard. When a project is transferred to the panel, only
the characters that are used in the panel are downloaded. If a character that is not
available is used, it is replaced by a black square, both in the configuration tool and
the operator panel. The project test that can be performed when transferring the
project checks that all used characters are present in the character set in the panel.
Character Sizes for User and System Texts
Unicode characters are processed as bitmaps (point matrices). The predefined char-
acter size is 8 x 16 pixels but can be changed. Sometimes the character size 16 x 16
must be chosen for complicated characters, such as those used in Chinese, to avoid
failure of certain pixels to be displayed and that characters be misinterpreted by the
operator. If a large character size is chosen, menu windows may not always have space
in small panels.
Switching between Display of Object Text and Index Number
When the T/@ button is selected on the Language toolbar, the configuration tool
displays the index number (@number) in the object instead of the text. In the @
mode, new text (in ANSI/OEM, not Unicode) can be specified to link the object to
a new index and release it from the other objects and the original index. By specifying
@number, the object can be linked to new indexes.
