ruby 1.9 internally is no longer 8 bit clean i.e. there is always an 
encoding (file as well as internal); there is no way to enforce this 
(there is the -E option but that is useless for 1.8)

i now open some files explicitly in binary mode; maybe that helps; i 
have no clue what happens with string manipulations later on

i always liked ruby but such fundamental changes (encoding, dropping 
functions etc) without renaming the program are a showstopper for me as 
one cannot predict what will be on the user's system

it looks like i have to convert the texutil part to lua (takes a few 
days and since i mostly use luatex it has a low priority)

i uploaded a beta for testing
