Detailed Description

To convert 'char' input/command line parameter to 'wchar_t'.

This class is to convert 'char' type command line parameter to wide-character (wchar_t) format and stores the copy of it. This is useful for all classes that use 'char**' argv but cannot be converted into 'ACE_TCHAR**' version. Note that the converted data will be lost upon destruction, so classes should use this class as their data member.
