DoubleByte TrueType Font Interface

DoubleByte TrueType Interface Installation

DoubleByte TrueType Font Interface

The DoubleByte TrueType Font Interface installs Asian DBCS TrueType(D- - 8) fonts compatible with the far east versions of Windows or Macintosh into Smart Characters for Windows. The interface works under with Windows 3.1 or higher, including Windows 95 and NT. It is the only method that supports simultaneously use of simplified(4- 10) and traditional Chinese and Japanese TrueType fonts in a document or session. See Setting up the DoubleByte TrueType Font Interface(13- 1) and Using DoubleByte TrueType Fonts(13- 3).

Setting up the DoubleByte TrueType Font Interface

The DoubleByte TrueType font interface(13- 1) ships with representative TrueType fonts registered as installed in Japanese, Traditional, and Simplified Chinese Windows. These registered font entries are used for demonstration and testing, and do not work unless (unlikely) you have the same far east Windows installations as the factory computer.

To setup the font interface, delete any entries that do not exist on your system (e.g., the factory entries), then install the fonts that are present. The fonts will then be available for use in the a document. See Using DoubleByte TrueType Fonts(13- 3).

Deleting TrueType Entries

(4- 11) that do not correspond to valid DBCS (double byte code system) TrueType(D- - 8) fonts display characters as blocks of vertical lines. To avoid clutter and confusion, delete their registration entries in two places: the Smart Characters system font(4- 13) table and the DoubleByte TrueType font interface installed font table:

MS-Gothic 11.Chars 48 (TrueType)
MS-Mincho 11.Chars 48 (TrueType)
MingLi43 15.Chars 48 (TrueType)
simhei19 16.Chars 48 (TrueType)
sming20 16.Chars 48 (TrueType)

Adding Windows TrueType Fonts

If you have Traditional or Simplified Chinese or Japanese Windows installed on your computer, you can install the TrueType fonts used by these far east Windows into the DoubleByte TrueType font interface by specifying their corresponding .FOT files, located in the \Windows\System directory: The font interface copies the font's Postscript name(D- - 6) to the Typeface Name edit control. You can accept the typeface(4- 11) name as is, or edit it. Suitable modification include adding a language code to the end of the font (e.g., -Jpn, -ChI, -Sim), deleting extraneous letters or numbers at the end of a long name, and deleting or moving a manufacturer's name. For example, "DFHSGothic-W5-WIN-RKSJ-H" could be changed to "Gothic-W5-Chi-DFHS". See Font Naming Conventions(13- 5).

g Separate TrueType Fonts Adding Separate TrueType Fonts

You can install Traditional or Simplified Chinese or Japanese TrueType fonts directly into the DoubleByte TrueType font interface by specifying the corresponding .TTF file, which can be located in any directory. Because this procedure does not automatically install associated bitmap fonts(8- 5), you should use this method only for Chinese character TrueType fonts that are not already installed into a far east version of Windows. Otherwise, see Adding Windows TrueType Fonts(13- 2).

Using DoubleByte TrueType Fonts

To use a DoubleByte TrueType font in a document, select it from the Typeface control in the Character Format(3- 16) dialog. If the font is not listed in the Typeface list box, register it in the document: The typefaces in a new document come from the document template selected with File | New. The factory defaults are Times New Roman for English and CombinedMing for Chinese Characters. To add typefaces to new documents, add them to the document template.

Changing Typeface Names

If you electronically transmit and receive Smart Characters documents, you may receive a document that uses TrueType(D- - 8) fonts that are not installed on your system, or are registered in the document under a different typeface(4- 11) name. An uninstalled TrueType font displays as squares of vertical stripes. There are two ways to display these characters: register the typeface name used in the document in the DoubleByte TrueType font interface, or change the typeface in the document to one that is installed on your system. Each method has advantages and disadvantages:

Registration of a typeface name used by another user has the advantage of allowing future transmissions to be viewed without further difficulty. The disadvantage is that you add a certain level of anomaly to your system by specifying the same font by different names, and that other users may then adopt the font naming convention used in the received document. A more serious anomaly arises when the typefaces do not match (e.g., using a Gothic typeface as a Ming typeface, or a light weight as a heavy weight).

Changing the typeface alters the document by substituting existing typefaces for missing ones. The advantage is consistency and clarity. The disadvantage is the extra step involved, and that you cannot check the document after restoring the original typeface names for retransmission.

Font Naming Conventions

Most word processors identify a TrueType(D- - 8) font by its TrueType name plus the code page(D- - 2) used to represent that name. This code page specific name cannot be displayed or selected on another system that does not have the code page installed. Fortunately, a TrueType font can also be identified by its internal Postscript name(D- - 6), which is always written in the English code page, using romanization. In order to handle fonts consistently regardless of installed code pages, the DoubleByte TrueType font interface identifies fonts by their postscript names, rather than by their language-specific TrueType names. However, the TrueType names are stored in the DoubleByte font interface initialization file for use in exporting text to native word processors.

The internal postscript names for the fonts shipped with Windows are listed below followed by their Smart Characters symbol set IDs and use:

Japanese MS-Gothic 1.Chars 48
MS-Mincho 1.Chars 48 Traditional MingLi43 5.Chars 48 (only one) Simplified simhei19 6.Chars 48
sming20 6.Chars 48
The internal postscript names ensure uniqueness, but are not intended for user selection. Some names from other manufacturers can be more or less descriptive, such as "DLCHeyMedium" or "DFTT-B5." You can name these fonts as you like, but your naming conventions would have to be used by others in order for another user to display the same fonts.
