(setq current-language-environment "UTF-8")这句话有什么作用？

I think you use it wrong. Normally people use,

(setq current-language-environment "English")

or,

(setq current-language-environment "Chinese-GB")

current-language-environment is a variable defined in `mule-cmds.el'. This variable should be set by using the function `set-language-environment'.

to set encoding to UTF-8, do

(prefer-coding-system 'utf-8)
