As I understand it, by default luatex accepts its input in UTF8.  However, the manual if \pdfoutput=1, fonts are limited to 256 glyphs.  What is the expected idiom for massaging the input so that non-ASCII UTF8 symbols can be displayed sensibly? Should I be putting a hook into the reader callback?  Or is there intended to be a more specific mechanism in the future? 

    Put another way, I have a LaTeX document that in conjunction with the inputenc package and pdftex-1.40.x-beta handles the occurrences of UTF8 in my document by replacing them with macros I've defined.  However, I don't expect inputenc works with lua{la}tex, and I'm trying to decide how to best port my document over.

    Thanks for any suggestions!
