Greetings -

I am using freetype2 to render Asian characters in a vertical layout. Although I am just beginning this task, I noticed that freetype seems to rotate all characters by 90 degrees when rasterizing in a vertical layout. Although this is desirable for latin characters, this is not what I want for Asian characters. I still want Asian characters to remain oriented upright and non-rotated.

Is the general assumption that it is the developer's responsibility to handle such cases? So, for Asian character ID's, I should not request vertical layout of freetype - yet if I do that, how do I get vertical metrics for proper layout? Is there some missing functionality in freetype that I am missing concerning the rotation of some characters in vertical layout? Any pointers or background knowledge would be helpful here and greatly appreciated.
