oXygen XML Editor supports a large number of text encodings. For example, Unicode 4 is fully supported in both the Text mode and Author mode.
oXygen is the first XML editor to offer complete support for languages that require right to left languages. This means that content authors editing documents in the oXygenAuthor mode are able to create and edit XML content in Arabic, Hebrew, Persian, Urdu and many others.
To achieve this, oXygen implements the Unicode Bidirectional Algorithm as specified by the Unicode consortium. The text arrangement is similar to what you get in an HTML browser. The final text layout is rendered according with the directional CSS properties matching the XML elements and the Unicode Directional Formatting codes.
With oXygen you can edit the source of right-to left XML documents. You can also change the text orientation, making the markup align to the right side of the editor.
The input methods for CJK text are fully supported. The editor displays an on-the-spot pop-up window with the composed text when the inserted characters belong to the CJK code pages. The composed text is shown in the context of the document that it will eventually belong to, in a style that indicates that the text still needs to be converted or confirmed by the user.
This is available for both Author and Text editing modes.
The oXygen user interface supports localization. In the same installation kit, together with the English base version there are shipped German, French, Japanese and Dutch versions as well.
