1、检查系统默认编码：

locale

显示：

LANG=zh_CN.UTF-8
 LANGUAGE= 
 LC_CTYPE="zh_CN.UTF-8" 
 LC_NUMERIC="zh_CN.UTF-8" 
 LC_TIME="zh_CN.UTF-8" 
 LC_COLLATE="zh_CN.UTF-8" 
 LC_MONETARY="zh_CN.UTF-8" 
 LC_MESSAGES="zh_CN.UTF-8" 
 LC_PAPER="zh_CN.UTF-8" 
 LC_NAME="zh_CN.UTF-8" 
 LC_ADDRESS="zh_CN.UTF-8" 
 LC_TELEPHONE="zh_CN.UTF-8" L
 C_MEASUREMENT="zh_CN.UTF-8" 
 LC_IDENTIFICATION="zh_CN.UTF-8"
  LC_ALL=

export LC_ALL=en_US.UTF-8
