The referred change has been done before branching off 1.8:

commit 0a28fb8f6a354aa9a446b6bf70733c305534e074
Author: Gerald Combs <gerald@xxxxxxxxxxxxx>

    Update the Qt byte view widget to reflect the recent changes in the GTK+
    byte view.

    Move the packet_char_enc enum from packet.h to frame_data.h. Make the
    encoding flag a packet_char_enc and make it one bit.

    Get rid of the "cfile" global in a few places. C++-ize some of the font
    code. Clean up some variable names.
