SACHARSET=charset;IQLANG=language_code
where charset is a valid character set label and language_code is a language code from the list of language label values in SQL Anywhere 11.0.1 > SQL Anywhere Server – Database Administration > Configuring Your Database > International languages and character sets > Understanding locales > Understanding the locale language.
