Re: [NTG-context] Automatic replacement?

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. Huseyin
