Failure to render this form correctly would result in a disjointed and unnatural appearance.
-
Medial Forms
In the middle of a word, Arabic letters typically connect to both the preceding and following letters. The medial form is adapted to facilitate this connection. For example, the letter “ain” () takes on a characteristic looped shape when connecting letters on both sides. The iOS font rendering engine is responsible for choosing the correct medial form from available glyph variations within the font data.
-
Final Forms
At the end of a word, an Arabic letter typically connects to the preceding letter but does not connect to any subsequent character. The final form reflects this terminal position. For example, the letter “ha” () often closes into a distinct shape when it appears at the end of a word. In iOS, proper rendering of the final form ensures a clear visual termination of the word.
-
Isolated Forms
When a letter stands alone, either as a single-letter word or due to being separated by non-connecting letters, it assumes its isolated form. The isolated form is often the most basic or representative shape of the letter. For instance, the letter “alif” () maintains a consistent vertical stroke regardless of context, though its connection behavior varies. The ability of the iOS system to correctly display this form is crucial for representing standalone letters and words accurately.
