java.lang.Objectcom.ibm.bidiTools.bdlayout.BidiConvert
public class BidiConvert
BidiConvert is a convenience class to facilitate invocation of the Bidi layout transformations by converter code in the JVM.
It contains 2 public methods: toUnicode() and toSbcs().
Method toUnicode() must be called by the ByteToChar converters after converting the SBCS byte data into Unicode.
Method toSbcs() must be called by the CharToByte converters before converting the Unicode string data into byte data.
