 class TBidiLogicalToVisual

 /** 

 This class is a low-level class for bi-directionally reordering text. It 

 allows the re-ordering of text using no leaving functions at all, and provides 

 a finer degree of control than TBidiText. However, it should not be used 

 without understanding the basics of the Unicode Bi-directional Reordering 

 Algorithm.
