Bidirectional Class - Right To Left

Right To Left is a bidirectional class value indicating that a character is inherently written from right to left, such as Hebrew, Arabic, Syriac, or Thaana letters. Characters with this value are treated as strong directional types, meaning they establish their own embedding direction in mixed text, overriding neutral characters like spaces or punctuation that appear between them. In a bidirectional algorithm, these characters are placed from the rightmost position toward the left, and their presence can affect the ordering of adjacent numbers or Latin text, causing them to reorder accordingly. For example, in a sentence containing both English and Arabic, the Arabic script flows rightward while English continues leftward, with the algorithm determining how the two segments interact at boundaries. This class does not include digits or weak types, which have separate handling, so it exclusively covers letters and symbols with an intrinsic right to left directionality.
