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.
