// Shape Arabic text on a character basis. // //

This function performs basic operations for "shaping" Arabic text. It is most // useful for use with legacy data formats and legacy display technology // (simple terminals). All operations are performed on Unicode characters.

// //

Text-based shaping means that some character code points in the text are // replaced by others depending on the context. It transforms one kind of text // into another. In comparison, modern displays for Arabic text select // appropriate, context-dependent font glyphs for each text element, which means // that they transform text into a glyph vector.

// //

Text transformations are necessary when modern display technology is not // available or when text needs to be transformed to or from legacy formats that // use "shaped" characters. Since the Arabic script is cursive, connecting // adjacent letters to each other, computers select images for each letter based // on the surrounding letters. This usually results in four images per Arabic // letter: initial, middle, final, and isolated forms. In Unicode, on the other // hand, letters are normally stored abstract, and a display system is expected // to select the necessary glyphs. (This makes searching and other text // processing easier because the same letter has only one code.) It is possible // to mimic this with text transformations because there are characters in // Unicode that are rendered as letters with a specific shape // (or cursive connectivity). They were included for interoperability with // legacy systems and codepages, and for unsophisticated display systems.

// //

A second kind of text transformations is supported for Arabic digits: // For compatibility with legacy codepages that only include European digits, // it is possible to replace one set of digits by another, changing the // character code points. These operations can be performed for either // Arabic-Indic Digits (U+0660...U+0669) or Eastern (Extended) Arabic-Indic // digits (U+06f0...U+06f9).

// //

Some replacements may result in more or fewer characters (code points). // By default, this means that the destination buffer may receive text with a // length different from the source length. Some legacy systems rely on the // length of the text to be constant. They expect extra spaces to be added // or consumed either next to the affected character or at the end of the // text.

// //

For details about the available operations, see the description of the // U_SHAPE_... options.
