You can change your default locale using the following procedure.
Choose the language button on the dtlogin window.
Select the C, zh, zh.UTF-8, zh_CN.GB18030 or zh.GBK locale.
Your new locale is in effect.
You can use aliases to change a terminal-emulation window between the Simplified Chinese and ASCII/English locale from time to time without typing long command lines or editing your .dtlogin file and running source every time.
