transformer based translation from language english(left-to-right) to language(right-to-left) language

[rabail kamboh]

hello everyone!

i am running fairseq transformer model (new model) to translation english to arabic language. as english is left-to-right written language and arabic is right-to-left written language. My question is if the transformers automatically handle this different written structure or we have to do some coding for position encodings??
