官方就有解决方法,这招可以解决目前所有的版本,全部文件将用UTF-8解码. 这是原文: For those who need to use international and multibyte characters, NetBeans can support UTF-8 editing. To enable it, go to your NetBeans installation directory and find the etc folder. There will be a file there called netbeans.conf . This file keeps some configuration for NetBeans, including the default command line arguments. These are parameters that will be sent to a new starting Netbeans IDE. Every argument lives inside a double-quoted variable called netbeans_default_options , and each one is separated from another by a space. To enable UTF-8 in NetBeans, just place this parameter anywhere on the list of netbeans_default_options:-J-Dfile.encoding=UTF-8 中文解释: 1.找到你的Netbeans安装目录下的etc文件夹,如C:\Program Files\NetBeans 6.0 M9\etc 2.用记事本打开netbeans.conf 3.找到netbeans_default_options这一句(没带#号的,带#号的是注释) 4.在最后面加上一个空格,再加入-J-Dfile.encoding=UTF-8 如我现在的设置: 这样,打开的文件所有都用UTF-8解码了~哈哈,不再有乱码咯~
