I am not that lucky, most of my old pdflatex documents fail. I often
have \everypar containing a macro with one parameter for setting an
initial. If I output it as {\otherfont #1} and the token is the first
octet of a multioctet character, it fails. Character V as an initial
needs an extra kern thus if the macro contains \if#1V and #1 is the
first octet of a multioctet character, it fails. I often use
\futurelet\testchar\dosomething and if \testchar becomes the first
octet of a multioctet character, \dosomething fails. And it happens
even without hyperref. I stopped using pdflatex a few years ago. Now I
have 15 versions of TeX Live installed and when I have to recompile an
old document, I go back in history and try, in which version of TL the
document works. It is quite common for me that he old pdflatex
documents do not work in the current TL.
