Question

Due to some awkward legacy code, I need to pass some non-English text around as ansi/ascii strings that are visibly UTF-8 encoded. For the most part, this is working alright (I m using URLEncoder). However, now I need it to be able to output different versions of UTF-8 in different circumstances, and I don t know how to do that.

For example, this character can be UTF-8 encoded these ways:

大
%u5927
&#22823;
%E5%A4%A7

But nothing seems to talk about the different versions, as though there is no difference. I know URLEncoder does not do the second version, because the & is a reserved character, but the second one is what I need in some instances. How can I convert the text to the specific version I want?

Specifically, it s being passed to a .jsp that contains a library called displaytag that handles the data and displays a table without much developer input, but it doesn t seem to have any options for setting the encoding. I know the second encoding (passed as ansi/ascii) in the above list is displays correctly without changing the .jsp, though, which is the safest option for me. I just need to get it that way.

Answer 1

First is the unicode code point in hex and is URL encoded, second is same in decimal and is the HTML/XML entity form.

Never used it for your purpose but I think StringEscapeUtils escapeHtml or escapeXml should give you the second form.

BTW the second form also has a hex version: 大

第三,看一看非图八人意识到的转变功能,这种转变使图八中分别构成单一编码点的三条 by子转变。我认为,第三点是不正确的,因为你看不到三点 by,或事实上是ut八。

Answer 2

From what I can gather from the question, all you really want to ultimately do is display text.

你已经知道,存储在记忆中或档案中的内容是按顺序排列的,纯粹是简单的,有些是,你有三重顺序,即5 a4 a7,因为这正是UTF-8编码的OOKIIOO HAJIM INI。

如果用 Java语将这种特性放在URL中,那么你使用URLEncoder,你将获得%E5%A4A7。但是,如果你想在联合项目上展示,我一定会建议超文本实体<代码>大。因为,如果你决定寄送UTF-8的原始tes子,那么,你们的电灯要由终端用户打上其 character子的 character子。

如何做到这一点,取决于贵数据是否作为直径储存,还是真正的 Java。一般来说,对于产出超额计数实体,你可以通过将每一特性与高于7F的代码相转换为形式特征,在方案上这样做。

& # x codepoint ;

或为你寻找图书馆。如果你处理一阵列,这或许会更多工作,但可以这样做。 Lang s StringE PinheiroUtils共同公司处理已知的指定实体,但我不认为这将为具有较大密码点的特性创建数字超文本实体。
