if you use those fonts indeed you need to map from input encoding to 
font encoding and active characters are the way to go then

the context distribution ships with plain font support in which case you 
can best use the lm fonts instead of csr (i can't even locate those files)

\font\csr=lmroman10-regular.otf:+liga;+kern at 10pt

% \font\csr=csr.afm:+liga;+kern at 10pt

\csr č \bye

and then somehging like:

luatex --fmt=luatex-plain \dump

luatex --fmt=luatex-plain yourfile.tex

(here i test plain code with:

mtxrun --script plain --make
mtxrun --script plain        yourfile.tex

but that assumes a context installation)

(alternatively you can write a simple font loader in lua that does the 
mapping)
