GB2312/GBK <br /><br />�q�就是汉子的国标码，专门用来表示汉字�Q�是双字节编码，而英文字母和iso8859-1一��_��兼容iso8859-1�~�码�Q�。其中gbk�~�码能够用来同时表示�J�体字和���体字�Q�而gb2312只能表示���体字�Q�gbk是兼容gb2312�~�码的�?<br /><br />2.3. unicode <br /><br />�q�是最�l�一的编码，可以用来表示所有语�a�的字�W�，而且是定长双字节�Q�也有四字节的）�~�码�Q�包括英文字母在内。所以可以说它是不兼容iso8859-1�~�码的，也不兼容��M���~�码。不�q�，相对于iso8859-1�~�码来说�Q�uniocode�~�码只是在前面增加了一�?字节�Q�比如字母a�?00 61"�?<br /><br />需要说明的是，定长�~�码便于计算机处理（注意GB2312/GBK不是定长�~�码�Q�，而unicode又可以用来表�C�所有字�W�，所以在很多软�g内部是��用unicode�~�码来处理的�Q�比如java�?<br /><br />2.4. UTF <br /><br />考虑到unicode�~�码不兼容iso8859-1�~�码�Q�而且�Ҏ��占用更多的空��_��因�ؓ对于英文字母�Q�unicode也需要两个字节来表示。所以unicode不便于传输和存储。因此而��生了utf�~�码�Q�utf�~�码兼容iso8859-1�~�码�Q�同时也可以用来表示所有语�a�的字�W�，不过�Q�utf�~�码是不定长�~�码�Q�每一个字�W�的长度�?-6个字节不�{�。另外，utf�~�码自带���单的校验功能。一般来�Ԍ��英文字母都是用一个字节表�C�，而汉字��用三个字节�?<br /><br />注意�Q�虽然说utf是�ؓ了��用更���的�I�间而��用的�Q�但那只是相对于unicode�~�码来说�Q�如果已�l�知道是汉字�Q�则使用GB2312/GBK无疑是最节省的。不�q�另一斚w���Q�值得说明的是�Q�虽然utf�~�码�Ҏ��字���?个字节，但即使对于汉字网��，utf�~�码也会比unicode�~�码节省�Q�因为网��中包含了很多的英文字符�?<br /><br />3. java对字�W�的处理 <br /><br />在java应用软�g中，会有多处涉及到字�W�集�~�码�Q�有些地斚w��要进行正���的讄����Q�有些地斚w��要进行一定程度的处理�?<br /><br />3.1. getBytes(charset) <br /><br />�q�是java字符串处理的一个标准函敎ͼ�其作用是���字�W�串所表示的字�W�按照charset�~�码�Q��ƈ以字节方式表�C�。注意字�W�串在java内存中��L��按unicode�~�码存储的。比�?中文"�Q�正常情况下�Q�即没有错误的时候）存储�?4e2d 6587"�Q�如果charset�?gbk"�Q�则被编码�ؓ"d6d0 cec4"�Q�然后返回字�?d6 d0 ce c4"。如果charset�?utf8"则最后是"e4 b8 ad e6 96 87"。如果是"iso8859-1"�Q�则�׃��无法�~�码�Q�最后返�?"3f 3f"�Q�两个问��P���?<br /><br />3.2. new String(charset) <br /><br />�q�是java字符串处理的另一个标准函敎ͼ�和上一个函数的作用相反�Q�将字节数组按照charset�~�码�q�行�l�合识别�Q�最后�{换�ؓunicode存储。参考上�q�getBytes的例子，"gbk" �?utf8"都可以得出正���的�l�果"4e2d 6587"�Q�但iso8859-1最后变成了"003f 003f"�Q�两个问��P���?<br /><br />因�ؓutf8可以用来表示/�~�码所有字�W�，所以new String( str.getBytes( "utf8" ), "utf8" ) === str�Q�即完全可逆�?<br /><br />3.3. setCharacterEncoding() <br /><br />该函数用来设�|�http��h��或者相应的�~�码�?<br /><br />对于request�Q�是指提交内容的�~�码�Q�指定后可以通过getParameter()则直接获得正���的字符�Ԍ��如果不指定，则默认��用iso8859-1�~�码�Q�需要进一步处理。参见下�q?表单输入"。值得注意的是在执行setCharacterEncoding()之前�Q�不能执行�Q何getParameter()。java doc上说明：This method must be called prior to reading request parameters or reading input using getReader()。而且�Q�该指定只对POST�Ҏ��有效�Q�对GET�Ҏ��无效。分析原因，应该是在执行�W�一个getParameter()的时候，java���会按照�~�码分析所有的提交内容�Q�而后�l�的getParameter()不再�q�行分析�Q�所以setCharacterEncoding()无效。而对于GET�Ҏ��提交表单是，提交的内容在URL中，一开始就已经按照�~�码分析所有的提交内容�Q�setCharacterEncoding()自然���无效�?/p></div>
