Working With The Transform For Double Byte Text Streams; What Are Dbcs Ascii And Euc - Ricoh InfoPrint Pro C900AFP Manual

The C language header file for all line-data transform exit programs is provided in
the install_path\exits\acif\apkexits.h directory, and the build rules for the
line-data transform user exits reside in install_path\exits\acif\exit_program.
The source code for the sample exits is provided in install_path\exits\acif. You
can modify these source files or create your own. You must have the Microsoft
Visual Studio 2005, installed on your InfoPrint Windows server to compile and
build user-exit programs. Be sure to apply the latest service available. Sample
project files for Microsoft Visual for each exit program are also installed in the
same directory.
For more information about compiling user exit programs, see "Configuring
transforms" on page 209.

Working with the transform for double byte text streams

InfoPrint Manager includes the db2afp transform, a program that transforms both
double-byte character set (DBCS) ASCII and Extended UNIX Code (EUC) files into
the Advanced Function Presentation (AFP) data stream.

What are DBCS ASCII and EUC?

In ideographic languages like Japanese, Chinese, and Korean, there are thousands
of characters. All of these characters cannot be represented with a single byte of
information because a single byte only accomodates 256 characters. Therefore, at
least one more byte of information is required.
In DBCS ASCII files, each ideographic character is exactly two bytes. In EUC files,
each ideographic character can be two, three, or four bytes, depending on the EUC
implementation and language. Single-byte ASCII characters can be mixed in with
DBCS and EUC characters.
InfoPrint Manager for Windows supports printing DBCS ASCII files in the
Japanese and Traditional Chinese languages, which can contain formatting controls
for the IBM 5577 or 5587 printers. InfoPrint Manager for Windows also supports
printing EUC files in the Japanese, Traditional Chinese, and Korean languages, but
you must submit those jobs from a UNIX or AIX workstation. EUC files cannot
contain any formatting control characters.
truncation. Adding a blank to other types of data files could cause
formatting errors, depending on how the page definition is coded.
2. This exit only checks for a single trailing blank, so if a different
number of odd blanks is present in the data, it is up to the user to
make sure the data is formatted with the correct font.
