// Shape Arabic text on a character basis.
//
// <p>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.</p>
//
// <p>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.</p>
//
// <p>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.</p>
//
// <p>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).</p>
//
// <p>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.</p>
//
// <p>For details about the available operations, see the description of the
// <code>U_SHAPE_...</code> options.</p>
