Looks good because URL beautifiers catch that, but the actual URL you linked is ar.m.wikisource.org/wiki/تفسير_ابن_كثير and relying on URL detection has proven to be very unreliable. For instance, Wikipedia links often lack closing parentheses, or closing parentheses and other punctuation get added to links accidentally.

Hex-encoded URLs are technically valid, but not very readable to humans.
