最近在做一个项目的时候,遇到了一个问题,香港服务器,在window 2003 系统oracle 11g数据库进行select的时候,结果为“靠靠靠靠”,当时的运维人员对oracle不太了解,所以就找到了我,我查看服务端与客户端的字符集,发现服务端为zhs16gbk,客户端为american_america.we8iso8858p1,当我把客户端修改与服务端一致字符集的时候,问题解决了。
下面是我做的一个技术文档,为以后的人员学习oracle做个实例说明。
环境为:
window 2003 32系统、oracle 11g数据库
1、连接windows 2003的oracle 11g
2、查看客户端的字符集
3、查看服务端的字符集
可以看到客户端与服务端的字符集都是一致的,均为ZHS16GBK。
4、创建dl_char表
5、插入数据
6、进行select查询
可以看得,现在显示为我刚才输入的值
7、更改客户端的字符集
8、然后重新登录
9、查看客户端的字符集
可以看到客户端的字符集已经变为AMERICAN_AMERICA.ZHS16GBK了
10、然后查看dl_char的值
现在就出现了我前面说的4个靠字的问题,网站空间,从上面的实验,可以看到产生4靠的原因为:客户端与服务端的字符集不一致,所以解决这个问题的方法就是在客户端设置与服务端一致的字符集
11、现在把客户端的字符集改成与服务端一致的字符集
12、然后登陆
13、查看客户端与服务端的字符集
14、现在客户端与服务端的字符集都一致了,在查看一下dl_char里的内容
现在显示为正常的、我之前输入的值了,美国空间,4个靠字也没用在出现,所以提醒大家一下,以后在做exp/imp导出/导入或者客户端查询数据等操作的时候,一定要把客户端的字符集与服务端的字符集设置为同一个。

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
