this is splendid. Adding support for the PDF "ActualText" tagging layer is a huge step. 

I wonder — what happens in case of mathematical formulae? 

I think it would be rather clever to embed the TeX notation or even, huh huh, MathML into the ActualText layer for the math mode — per equation, of course :) . Or use the "Unicode math linear format" as proposed by Microsoft:

> Akira, if you could check that the patch seems OK, that would be great. I've not really looked at dvipdfm-x code in a long time. I haven't pushed this it to TL yet, as it's all rather experimental, but I hope we can safely include it for TL'16.
