ColdFusion is implemented in Java. As a Java application, ColdFusion uses Java globalization features. For example, ColdFusion stores all strings internally using the Unicode character set. Because it uses Unicode, ColdFusion can represent any text data from any language.

In addition, ColdFusion includes many tags and functions designed to support globalizing your applications. You can use these tags and functions to set locales, convert date and currency formats, control the output encoding of ColdFusion pages, and perform other actions.
