Thanks luigi, but it does not work for my characters, see here:

\definefont[tradoa][name:**trado*arabic at 20pt] % or file:amiri-regular.ttf*... file:alq.ttf

\directlua{ local function replace_txt (buffer) buffer=string.gsub(buffer,"**اللهِ","اللَّـه") return buffer end callback.register("process_**input_buffer",replace_txt) } \starttext my text {\setupalign[r2l] \tradoa اللَّـه} \stoptext

"trado" ist just the font "traditional arabic", nearly every system have it, so you should be able to compile this. It does not replace the character.

ok, I've installed amiri-regular.ttf and it compiles, and as you say the gsub doesn't work. I'm trying to see why. -- luigi

my fault, sorry. In the string library the function are not unicode aware (of course, I should say...) .
