More sophisticated replacements are those driven by the context. In principle all replacements can be context driven, but the calt and clig features are normally dedicated to the real complex ones that take preceding and following characters into account. analyze=yes, calt=yes, ccmp=yes, features=yes, fina=yes, init=yes, isol=yes, kern=yes, language=dflt, mark=yes, medi=yes, mkmk=yes, mode=node, script=arab ‎ه ِ ‎ه اَل ‏ُدْمَ‏ ‏ْح ‏ًرا؛ اَل ‏ْيِ‏ ‎ذ ‏َوال ‏َسْجَ‏ ‏ْأ ‏ٍفِ‏ ‏َر ‏َق ال ‏ْموَ‏ امَ،‏ ‏َوالذ‎كْرَ‏ ‏َوال وةَ،ٰیَ‏ ‏ْح ‏َوالن ‎س ‏ْیانََ‏ ‏َرفِ‏ ‏َوالش‎ ر‎ ‏َوال ‏ْخيَ‏ ‏َوالش‎ ر‎ ‏َوالن ‏َعْ‏ ‎ف انِ‏ الث‎ن ‏ِءۤ‏ ‏َا ‏َوالض‎ ر‎ ‏َوالس‎ ‏َشاكِرً‏ ا،‏ ‏َوحُسِْل ‏َوال ‏ْحرَ‏ ‏ِن ، ، َ ‏ْر ، . ‏َوال ‏ْأرَ‏ اَل ‏ُدْمَ‏ ‏ْح ‏َواحَ‏ ‎ه ‏ًرا؛ اَل ‏ْيِ‏ ‎ذ ‏َوال ‏َسْجَ‏ ‏ْأ ‏ٍفِ‏ ‏َر ‏َق ال ‏ْموَ‏ امَ،‏ ‏َوالذ‎كْرَ‏ ‏َوال وةَ،ٰیَ‏ ‏ْح ‏َوالن انََیْ‏ ‎س ‏َرفِ‏ ‏َوالن ‏َعْ‏ ‎ف ‏َوال ‏ْخيَ‏ انِ‏ الث‎ن ‏ِءۤ‏ ‏َا ‏َوالض‎ ر‎ ‏َوالس‎ ‏َشاكِرً‏ ا،‏ ‏َوحُسِْل ‏َوال ‏ْحرَ‏ ‏ِن ، ، َ ‏ْر ، . ‏َواحَ‏ ‏َوال ‏ْأرَ‏ Ligatures are <strong>of</strong>ten used to beautify Arabic typeset documents.

Kerning deals with horizontal displacements, but curs (cursive) goes one step further.
