Both give 0.

For completeness here are the relevant results from fntest.log:

assert (isprint (charset),result) expected
 Columns 1 through 22:

   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0 
0   0   0   0   0
:
but got
 Columns 1 through 22:

   0   0   0   0   0   0   0   0   0   1   0   0   0   0   0   0   0 
0   0   0   0   0

But:
octave.exe:2> isprint ( "\t")
ans =  1

so it is TAB that is considered printable. Sorry for my miscounting.
BTW isprint ("\t") does the same on octave-3.6.2_MinGW and 3.4.3_MinGW.
Apparently the test is wrong.
