end
function love.draw()
love.graphics.print("عَرَبِيّ")
end

Apart from you using a file hoster that doesn't support hotlinking and probably infects computers with viruses, i don't see the issue in your image; is your issue related to the text not having the correct writing direction, or to the glyphs not using their correctly connected forms?
Edit: From what i can see from google translate, seems to be both of those issues simultaneously.

LÖVE doesn't support RTL rendering, or Arabic character joining. It uses only FreeType, not something that is Arabic-aware like Harfbuzz.
You could try to implement a library that is able to render Arabic.

In addition to the letters being reversed, for Arabic I think they are disjointed into individual characters. I believe with Arabic the individual glyphs should be joined.
It's a real nightmare, I had to do a Hebrew translation of Super Chains and was forced to reverse the characters manually. The worst is where bidirectional text is involved! In that case you have to split the string into LTR and RTL (based on the UTF8 code range) and reverse each part individually!!!
While I admit this is a rare issue it would be good if this is addressed in future versions of Love2D.

You are right! Yes, both of those issues simultaneously.
