Running setlocale() in your program is not the same as exporting
an environment variable. The call to setlocale() in your own program
will not affect the locale of the program you are spawning via popen().
Try setting the environment variable in your crontab instead.
Put this in your crontab:
LC_ALL=en_US.UTF-8
* * * * * /root/test >> /var/log/test.log 2>&1
I think that should work. Most cron programs support setting environment
variables like this.
