Terminal output of a deal shows '?' instead of unicode suit symbol or letter

[Chris Schoonbee]

When I invoke `deal` in a Gnome terminal, the output of the hands displays a '?' character where I would expect either a letter representing the suit eg 'S', 'H', 'D' or 'C' or else the unicode suit symbol eg ♠.

My terminal is capable of displaying unicode symbols eg I can type in ♠ at the command line.

Interestingly, if I specify the practice-hand format, then it outputs suit letters eg S, H, D, C, and not '?' characters. Although, in what may be another bug I have to use the following command:
$ deal -i /usr/share/deal/format/practice 8
instead of, as given in the instructions,:
$ deal -i format/practice 8
ie I have to specify the full path to the format file.
