Hi Eli,

Sorry for the delay.

Looks like I see the same as you.  With a file named "ÃÃÃ.c":

(gdb)
set print sevenbit-strings on
&"set print sevenbit-strings on\n"
=cmd-param-changed,param="print sevenbit-strings",value="on"
^done
(gdb) start
...
*stopped,reason="breakpoint-hit",disp="del",bkptno="2",frame={addr="0x00000000004004fb",func="main",args=[{name="argc",value="1"},{name="argv",value="0x7fffffffd838"}],file="\303\247\303\252\303\241.c",fullname="/home/pedro/gdb/tests/\303\247\303\252\303\241.c",line="5"},thread-id="1",stopped-threads="all",core="2"
(gdb)

(gdb)
set print sevenbit-strings off
&"set print sevenbit-strings off\n"
=cmd-param-changed,param="print sevenbit-strings",value="off"
^done
(gdb) start
...
*stopped,reason="breakpoint-hit",disp="del",bkptno="3",frame={addr="0x00000000004004fb",func="main",args=[{name="argc",value="1"},{name="argv",value="0x7fffffffd838"}],file="ÃÃÃ.c",fullname="/home/pedro/gdb/tests/ÃÃÃ.c",line="5"},thread-id="1",stopped-threads="all",core="2"




But with a file named "ÎÎÏÏÏÎ.c" + "set print sevenbit-strings off":

*stopped,reason="breakpoint-hit",disp="del",bkptno="1",frame={addr="0x00000000004004fb",func="main",args=[{name="argc",value="1"},{name="argv",value="0x7fffffffd808"}],file="ÎÎï\216ï\203ï\203Î.c",fullname="/home/pedro/gdb/tests/ÎÎï\216ï\203ï\203Î.c",line="5"},thread-id="1",stopped-threads="all",core="3"
=breakpoint-deleted,id="1"
(gdb)

I don't know.
