We have a Windows application (TCL script really) that wants to find the
IP address of the PC it runs on; it effectively does
cmd /c "ipconfig > ip.txt"
then reads the file. This works fine everywhere, except... I have a user
with WinXP set to Chinese language. For this user, the file stops after
"Ethernet adapter" (contains just 53 characters). Doing ipconfig without
redirection in a CommandPrompt window works fine and says the equivalent
of "Local Area Connection" in Chinese.
Seems to me that file I/O redirection, angle-brackets or pipe symbols,
stop at the first non-English character. Is this a known bug or feature?
If so, does anyone know a workaround? Otherwise, does this have security
implications?
Cheers,
