I think what would make most sense if for C-x = to notice such invisible
text and either give info about the whole invisible area, or prompt
which position within that area is actually desired.  In your case, you
want info about the visible char, but I most often use C-x =
specifically to get info about the part I can't see.

That can be configured via `cursor-type'.

Your call, but you've been warned.  I'd still recommend you first try it
without `intangible'.
