It's redundant.  We should deprecate it and add another, redundant,
vertical-orientation property.  That will be useful by HarfBuzz clients,
for segmenting vertical text.  Having it in hb-unicode is handy because
client code can interact with hb-unicode API only.

Does that make sense to you?

Hi Behdad,

Just wondering about hb_unicode_eastasian_width, and the underlying
support for it in the unicode_funcs AFAICS this is not currently
used in any way. (Or am I forgetting something important?)

Do you have plans for this at all, or is it truly redundant?

Yes, sounds fine. (For now, I mostly wanted to check whether removing 
our current implementation of the EAW callback might be something we'd 
regret later.)

Right.  I'll go ahead and deprecate it.  I don't think anyone ever used it.
