* @brief To convert 'char' input/command line parameter to 'wchar_t'.
*
* This class is to convert 'char' type command line paramter 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.
