Re: [PATCH v2 0/1] MR5633: win32u: Fallback to default script if vert/vrt2 is not found.

[Nikolay Sivov (＠nsivov)]

I don't know how it works with gdi, for directwrite there is GetVerticalGlyphVariants() that uses first 'vert' feature it finds, it does not have script/lang arguments. When it goes through full shaping, similar to ScriptShapeOpenType(), it will likely prioritize for given script/language.
