<p class="MsoNormal">Pipe vs. file differences would probably be the realm of the shell you are running under, not ipy. To ipy, its just stdout.<o:p></o:p></p>

<br>
Iron Python is pretty wonderful, but it gave me very confusing output. It<br>
likes Unicode. But I don't want Unicode output. All my output (as part of<br>
a processing chain) are numbers and spaces. ASCII is good for this (and<br>
that's what the other tools want.)<br>
<br>
If I run a simple command and send the output to a file I get Unicode. But<br>
the exact same command when sent to a pipe gives me ASCII. ARGGHH. Took<br>
me a long time to figure out this simple test case.<br>
<br>
This behavior should be (better) documented. Hopefully this email will save<br>
somebody else a lot of head scratching.<br>

- Malcolm<br>
P.S. The example below uses the Gnu on Windows command od to display the<br>
actual contents of the file in hex. The first example shows ASCII output,<br>
while the second output looks like Unicode to me.<br>
<br>
<br>
<br>
PS Z:\PitchTracking> ipy64.exe -c "print 'hello'" | od -x<br>
0000000 6568 6c6c 0d6f 000a<br>
0000007<br>

PS Z:\PitchTracking> ipy64.exe -c "print 'hello'" > junk<br>
