support for code page 930 to read japanese characters

Trying to read an ebcdic file received from main frame system using a copy book. The data has address lines which have Japanese characters. When reading the values are coming as blank - [, , , , ]. For Japanese characters we cannot pass code page 930 since only common (default), common_extended, cp037, cp037_extended, cp875. *_extended code pages are supported as of now.
Rest all data is read correctly except this.
