To change the default character set, sort order, or language, read Chapter 7, “Configuring Character Sets, Sort Orders, and Languages” and Chapter 8, “Configuring Client/Server Character Set Conversions,” in the System Administration Guide. This book can be found online at Sybooks.
A simplified procedure for doing this is included here.
Adaptive Server supports a wide variety of character sets, and you can localize error messages to suit your user community. By default, Adaptive Server is installed with a default character set of iso_1 (ISO 8859-1), a binary sort order, and English as the default language. All of these can be changed as required, as described in this section.
