Nagios Alert in Japanese

I have googled for weeks now and all I am getting is the same results from frank4dd's notes on setting up perl script to produce alerts in Japanese. On the contrary I wish to ensure all my alerts come in English as primary language. What I am getting from Japanese-language-Windows-machine added into Nagios are garbled tickets in English and characters. So how do I ensure that all the alerts will be produced in English?

I have Nagios installed on Suse and this is my distro level:

my-mnag1:/usr/local/nagios/libexec # cat /proc/version
Linux version 2.6.32.12-0.7-default (geeko@buildhost) (gcc version 4.3.4 [gcc-4_3-branch revision 152973] (SUSE Linux) ) #1 SMP 2010-05-20 11:14:20 +0200

whenever i execute the script i get this alert, i am not sure what to do! I am at my wits end trying to get this sorted out right

my-mnag0:/tmp # ./nagios_send_service_mail.pl
