qPad

If you're looking for a simple and lightweight note-taking and text editor for Windows that can support Right-to-left languages such as Arabic, Persian, and Hebrew, then you might want to check out qPad! As a Unicode enabled software, it allows you to start your paragraphs with these languages by making them right-aligned, making it a good alternative for Windows' Notepad.

qPad has been built using C++/Qt and can run on all Windows versions without requiring any installations. Unlike other editors that are electron-based, it has a very quick startup time and takes up the least memory possible, making it a reliable option for your note-taking needs.

One of the features that make qPad stand out is its ability to detect a file's encoding when you load it. If the file has an encoding other than UTF-8, a list of possible encodings shows up, allowing you to open the file with the proper encoding, which is a great time-saver!

Another handy feature of qPad is its Find and Replace tool that lets you search for multi-line expressions and replace them with another expression. If you're typing in Arabic or Persian languages, you can keep 'Match Alef Hamza' unchecked to make the search more flexible.

Overall, qPad is a great option if you're looking for a simple and reliable text editor that supports RTL languages and comes loaded with handy features like encoding detection and Find and Replace. Try it out for yourself!
