1. In order to use the Sybase datatypes unichar and univarchar, the Sybase Adaptive Server character set must be set as UTF-8.

2. When installing the Sybase client, all required locales, localized messages, and character sets must be installed.

3. Depending on the operating system locale, the values for the environment variables described in Internationalization and Localization should be specified correctly. These environment variable values and the vendor locale values mentioned in the locales.dat file located in the directory <Sybase home directory>/locales should match. For information on setting up the correct values of the environment variables, please see the Sybase International Developer’s Guide for Open Client/Server.
