  <p>The Arabic script is cursive. This means that letters appear in different forms depending on how they join with their neighbors. Majority of modern software implementations treat Arabic text accordingly. However, for few advanced typographic behaviours, additional considerations are required; for example, adding color highlighting to individual letterforms in a word context without disrupting the joining behaviour, application of text outlining, etc.</p>
