终端模式下“ ”都显示为?，请问如何解决？

比如我在终端下输入：man nmap显示如下：
Nmap (?Network Mapper?) is an open source tool for network exploration
       and security auditing. It was designed to rapidly scan large networks,
       although it works fine against single hosts. Nmap uses raw IP packets
       in novel ways to determine what hosts are available on the network,
       what services (application name and version) those hosts are offering,
       what operating systems (and OS versions) they are running, what type of
       packet filters/firewalls are in use, and dozens of other
       characteristics. While Nmap is commonly used for security audits, many
       systems and network administrators find it useful for routine tasks
       such as network inventory, managing service upgrade schedules, and
       monitoring host or service uptime.

       The output from Nmap is a list of scanned targets, with supplemental
       information on each depending on the options used. Key among that
       information is the ?interesting ports table?..

我的系统环境为:

直接在控制台还是ssh上去的?

直接在控制台下操作的，没有使用ssh

那你试试putty上去,字符编码选utf8看看

选了也不行，在ssh里显示的不是？了，而是乱码

chenyx

你的putty的编码是utf8的?
