node.js win7使用telnet只能单字符显示

Question

写的代码如下，每次telnet localhost 3000后输入字符，都只会单字符显示，且格式错乱？求解，问题出在哪里？

var net = require('net')
var count=0,users={}
var server = net.createServer(function (conn) {
    conn.setEncoding('utf8')
    var nickname;
    conn.write(
        '\n>welcome to node-chat!'
        +'\n >'+count+'other people are connected at this time.'
        +'\n > please write your name and press enter:'
    );
    count++;
    conn.on('data',function(data){
        data=data.replace('\r\n','')
        if(!nickname){
            if(users[data]){
                conn.write('\033[93m> nickname already in use.try again:\033[39m');
                return;
            }else{
                nickname=data
                users[nickname]=conn
                for(var i in users){
                    users[i].write('\033[90m>'+nickname+'joined the room\033[39m\n');
                }
            }
        }else{
            for (var i in users){
                if(i!=nickname){
                                   users[i].write('\033[96m>'+nickname+':\033[39m'+data+'\n');
                }
            }
        }
    })
    conn.on('close',function(){
        count--;
        delete users[nickname];
    })

})
server.listen(3000,function(){
    console.log('\033[96m server listening on *:3000\033[39m')
})

显示效果如图：
