International Language Support

There exists the notion of the language id, which is simply a value that assists the application in laying out the text. The tags that help with this are the language id tag and the alternate language id tag. Together, these allow the file format to be robust and handle multiple languages for a single run of text. In addition, there is also the kumimoji tag, which aids with the layout of East Asian text by specifying whether numbers appear vertically with text (default) or horizontally. An illustration of a run of text with kumimoji applied is provided below.
