0xFB6

0xFB6 refers to the Unicode scalar U+0FB6, a character in the Arabic Presentation Forms-A block (Unicode range U+FB50 to U+FDFF). This code point encodes a ligature for Arabic script and is part of a set of presentation form characters that were included to support legacy typesetting systems and older encodings before full Unicode text shaping was common.

In practice, U+0FB6 represents a specific ligature formed by combining individual Arabic letters. The exact letters and ligature form are defined in the Unicode standard and can vary by font; rendering engines typically apply ligatures automatically when the base letters are present, so the presentation form character is rarely used in new text.

Because these forms are compatibility characters, modern Unicode usage generally prefers representing text with the underlying base letters and relying on font shaping to produce the ligature. This improves text processing, searchability, and interoperability across platforms and fonts.

Usage considerations: U+0FB6 and other Arabic presentation forms are mainly encountered in older documents, fonts, or data that preserve legacy encoding mappings. For new content, it is recommended to use standard Arabic letters and allow font technologies to apply ligatures as needed, rather than embedding presentation form code points.

Related: The range U+FB50 to U+FDFF encompasses Arabic presentation forms; other blocks in the Unicode standard cover Arabic letters and ligatures used in modern typesetting.
