To create a document that contains multiple languages, use the #include action.
Use an application that supports UTF‑8 encoding, such as Dreamweaver, to save the text file in UTF‑8 format.
To identify the file as Unicode to the Flash authoring tool, include the following header as the first line of the file:
//!-- UTF8
By default, the Flash authoring application assumes that external files that use the #include action are encoded in the traditional code page of the operating system running the authoring tool. Using the //!-- UTF8 header in a file tells the authoring tool that the external file is encoded as UTF‑8.
