<p dir="auto">I can write Persian text (almost same as Arabic) in Atom even though it does not appear right to left. I can live with it, the problem is when I try to edit the text and I position the cursor somewhere inside the text and begin to type, the characters appear somewhere else, a few characters away.</p>
<p dir="auto">To show you a good example of correct behavior I should mention <em>gedit</em>. Using <em>gedit</em> to write Persian blog posts in markdown format, I have no problem entering and editing the text. Everything works as expected, I don't know which GUI component is being used in Atom and Gedit, probably that's the difference. Here are some screenshots showing the texts but I have no way to show the typing problem.</p>

<p dir="auto">Support for Unicode is incomplete. Unicode characters are shown, but the cursor get stuck, and the navigation with the keyboard arrows stop working.</p>
