Your site content is supported in any Language, we just need to enable the site to recognize the encoding. Please note that on some designs the menu items or page and section titles may not work with some specific encodings. Full multi-language support for these areas is included in upcoming releases.
The entire Site Encoding can be changed from Control Panel > Site Properties > Special Features
The Page Encoding for individual pages can be changed in the Page Options > Additional Options section
If the user has the ability to type the Alternate Language Encoding with their keyboard, they can type the content directly into the editor. They can also Copy/Paste content as long as it is in the correct encoding that they set for the page/site.
