What are good text editors with RTL (right-to-left) support?

In today's globalized world, the need for text editors that support right-to-left (RTL) languages has become increasingly important. RTL languages, such as Arabic, Hebrew, and Persian, are written from right to left, which can be challenging for text editors that are designed for left-to-right (LTR) languages. In this article, we will explore some of the best text editors that support RTL languages, with a focus on Ubuntu.

Understanding RTL Support

Before we dive into the text editors, it's essential to understand what RTL support entails. RTL support refers to the ability of a text editor to correctly display and edit text in RTL languages. This includes features such as:

Directional text rendering: The ability to render text in the correct direction, from right to left.
Bi-directional text support: The ability to handle text that contains both LTR and RTL scripts.
RTL-aware syntax highlighting: The ability to highlight syntax in RTL languages correctly.

Text Editors with RTL Support

1. Vim

Vim is a popular text editor that has been around for decades. While it may not have RTL support out of the box, it can be enabled with a few tweaks. To enable RTL support in Vim, you need to install the vim-ruby package and add the following lines to your ~/.vimrc file:

set encoding=utf-8
set fileencoding=utf-8
set langmap=abc,ABC

This will enable RTL support in Vim, but it may not work perfectly for all RTL languages.

2. Emacs

Emacs is another popular text editor that has RTL support built-in. To enable RTL support in Emacs, you need to add the following lines to your ~/.emacs file:
