Description of Issue:

East Asian established typography defines that a small amount of visible space between East Asian scripts and other scripts improves readability.

While detailed rules of the spacing can vary across documents, it is important that the choice made by an author for a specific document be clearly established, so that a rendering system can display what the author intended. It is also important that this choice be established independently of the font resources, as the rendering systems may have to use other fonts than those intended or specified in the document. Finally, the expression of the author’s choice should be relatively concise, to facilitate document authoring and minimize document size.

This draft report describes an algorithm and data which can be used to automatically add visible space.

The intent is that an author should be able to specify where they want to override, and that in the absence of an explicit specification, the spacing is applied according to this specification.
