Hi there, we do actually support right-to-left languages, but it might be that the language isn't set correctly on the source site or that our automatic detection doesn't detect it correctly. Here's an example of how Push to Kindle handles Persion on the BBC Persian site: https://pushtokindle.fivefilters.org/send.php?url=http%3A%2F%2Fbbcpersian.net%2Fn%2Fq%3D12293

If you're trying to process an article where the language isn't handled correctly, please leave a note on our forum and we'll be happy to take a look: https://forum.fivefilters.org/c/push-to-kindle/5
