That won't work for EBCDIC.

All strings are kept as UTF-8 internally to Wireshark; this means that Wireshark translates them from the character encoding in the packet to UTF-8, and therefore that Wireshark must be told what the encoding for the field is.

Therefore, you should do

        tree:add_packet_field(pf_mgi_flag, tvbuf:range(19,1), ENC_EBCDIC)

to add it to the protocol tree.

To fetch the actual string, you'd need to do

        local mgi_flag = tvbuf:range(19,1)
        local info_mgi_flag = mgi_flag:string(ENC_EBCDIC)
