The virtual body is usually a full-width square, no problem with that.
But it seems to be borrowing Ascender and Descender as vertical metrics. As who often works on Chinese fonts with Latin letters, I have to temporarily modify Ascender and Descender to get a correct CJK virtual body guideline.
Is it possible to add a custom parameter to define the top and bottom of virtual body guideline? Or add the vertical metric info as value in “CJK Guide” parameter?
Thx.
