Arabic doesn't render correctly

Hi, I use vim inside the terminal and it renders Arabic correctly. But I'm missing MacVim features. I was wondering if MacVim is using CoreText, then why Arabic is rendered incorrectly?

Take the following words for example, if you check the vim 8 in terminal it should display it as you can see it in your browser (if you have already executed set noarabic).

عربی فارسی

‌But in MacVim, the Arabic text is rendered from left to right. I saw there is an issue already posted here #696, but was it fixed?

まず、MacVim でのアラビア語の表示を再現し、例の単語を使って terminal Vim およびブラウザーと比較します。以前の調査については関連する issue #696 を確認してください。MacVim でアラビア語のテキストが正しく右から左に表示されれば完了です。
