ruby without rp not correctly handled

[acli]

There is currently a proposal to deprecate the rp element. If the rp element disappears, w3m will no longer be able to handle Japanese text with ruby correctly, which would result in the ironic situation that a Japanese browser is not able to handle Japanese text.

According to a comment (by Tab Atkins) in that proposal, rp is not currently recommended so rp-less ruby might already exist in the wild.

If you don’t have objections I’ll assign this to myself and try to tackle this in the next couple of weeks.
