Unicode Support
Unicode Support in IBM SPSS Modeler
IBM® SPSS® Modeler is fully U nicode-enabled for both IBM ® SPSS® Modeler and IBM®
SPSS® Modeler Serv er. This makes it possible to exchange data with other applications that
support Unicode, including multi-lang uage databases, without any lo ss of information that might
be caused by conv ersion to or from a locale-specific encoding scheme.
SPSS Modeler stores Unicode data internally and can read and write multi-language data
stored as Unicode in databases without loss.
SPSS Modele
r can read and write UTF-8 encoded text files. Text file import and export
will default to the locale-encodi ng but support UTF-8 as an alternative. This setting can be
specified in the file import and export nodes, or the default encoding can be changed in th e
stream properties dialog box. For more information, see the topic Setting general options
for streams in Chapter 5 on p. 55.
Statistics, SAS, and text data files stored in the locale-encodin g will be converted to UTF-8 on
import and back aga in on export. When writing to any file, if there are Unicode characters
that do not exist in the locale character set, they will be substituted and a wa rning will be
display ed . This should occur only where the data has been imported from a data source that
supports Unicode (a database or UTF-8 text file) and that contains characters from a different
locale or f
rom multiple locales or character sets .
IBM® SPSS® Modeler Solution Publisher images are UTF - 8 encoded and are truly portable
betwee n platforms and locales.
About Unicode
The go al of the Unicode standard is to provide a consiste nt way to encode multilingual text so that
it can be easily shared across borders, locales, and a pplications. The Unicode Standa r d, now at
version 4.0.1, defines a character set that is a superset of all of the character sets in common use
in the world today and assigns to each cha r acter a un ique name and code point. The characters
and their code points are identical to those of the Universal Character Set (UCS) defin ed by
ISO-10646. For more infor mation, see the Unicode Home Page (http://www.unicode.org).
