Do you think that HTML5 should support bad markups?
I don't think so.

This is not a problem.
Of course, the first one is better.
But, the second one is based on markup which is not good.
The markup blow is better, as I mentioned previously.


It will be read "ka-n-ji-bracketopen-ka-n-ji-bracketclose" by screen-readers which don't support <ruby>.
It is not best, but still is understandable.
My solution is progressive enhancement.
Screen-readers which support <ruby> will be able to read "ka-n-ji".

I don't want to say that you should use <rp>.
I think that your solution is also good.
I simply want <rp> not to dropped from HTML5.
It's better that we have alternative markup ways for a ruby.

Thank you.
