一朋友在升级SQL Server 2014后， SQL Server启动不了，寻求我的帮助。检查SQL Server 2014的错误日志，具体错误信息如下：

解决问题：

刚开始我以为是SQL Server升级过程中遇到错误，后面仔细检查错误日志，发现我忽略了一个重要的错误信息“The code page 65001 is not supported by the server.”，code page 65001对应的编码为UTF-8，而数据库排序规则为Chinese_PRC_CI_AS，对应的code page为936。原来这台SQL Server 数据库服务器的操作系统为Windows 10（个人还从未在Windows 10上安装过SQL Server，不得不说，千奇百怪的环境总会带来千奇百怪的问题！！），而它的服务器的“区域设置”勾选了支持UTF-8编码，所以只需在 ControlPanel -> Region -> Administrative -> Change System Locale 下取消如下截图的选项，重启服务器后，问题解决。
