Kathey Marsden commented on DERBY-728:
--------------------------------------
Thanks Tiago for the patch, I think the naming of the methods is a bit
confusing in the CCSidManger classes the method for example, public String
convertToUCS2(byte[] sourceBytes) should probably just be convertToJavaString
as as best I can tell that is what it is trying to do. So instead of:
String sourceString = new String(sourceBytes,"UTF-8");
return new String(sourceString.getBytes("UTF-16"),"UTF-16");
I think you could just return sourceString, unless I am missing something
entirely.
I don't see that the CcsidManger numToCharRepresentation is being used
anywhere. Could that just be removed?
