Hello,
I just started with gprolog and I'm following a tutorial that is wrote
in Hungarian language. This is not a tutorial for gprolog, but for
SICStusProlog.
A program in this tutorial is like the SICStusProlog_unicode.pl:
<file>
apja('Ábrahám','Izsák').
apja('Ábrahám','Ismeretlen').
apja('Izsák','Jákób').
apja('Ábrahám','Ismáel').
apja('Izsák','Ézsaú').
anyja('Sára','Izsák').
anyja('Rebeka','Jákób').
anyja('Hágár','Ismáel').
anyja('Rebeka','Ézsaú').
férfi('Ábrahám').
férfi('Jákób').
férfi('Izsák').
férfi('Ézsaú').
férfi('Ismáel').
nő('Sára').
nő('Ismeretlen').
nő('Hágár').
nő('Rebeka').
</file>
I can to consult this file:
| ?- ['SICStusProlog_unicode'].

(3 ms) yes
| ?-
but when I'm trying to query this program with:
| ?- apja(’Ábrahám’,’Izsák’).
I can't write down the 'Á' character ( without quotes ), the xterm beeps:
| ?- apja('
at the abowe point.
So, I think that that Gprolog doesn't have support unicode? Right?
