Language Property of Text Field

Do you know how to programmatically (Formula or Script) change the spelling language of text?

From Notes Help: In Notes 6.x Client, there is a new feature to tag text in a document as a specific language. The language tag is applied to text using the Font tab of the Text properties box. When text has a language tag it automatically will be Spell checked with the dictionary of the tagged language.

This works fine from the client, but there doesn’t seem to be a way to program it. I’ve been unable to find a function, method or property to get a handle to an RTitem’s spelling language. I figure it would be part of the NotesRichTextStyle Class, Range, or something… but I don’t see it.

Anyone have an idea of how I can add text to a RichText field and then change the “Language” property?

Thanks,
