that's no solution .. you cannot assume that the file that has the 
patterns is the one in control over the loading so for luatex/xetex one 
needs just patterns in utf and setting callbacks and such is not 
something that is likely to happen in user files (like patterns) outside 
a kind of infrastructure provided by the macropackage

for traditional tex one can use wrappers (macro package dependent btw) 
to read utf (context for instance ships with a set of patterns in utf 
format and uses them for pdftex/xetex/luatex) or one can ship the set in 
the (often one) font encoding used
