如何知道字符串编码在C＃ [英] How to know string encoding in C#

问题描述

我从一个第三方程序得到一个我不能控制的字符串。我的一段代码在HTML中输出。这在英语工作很好，但在其他语言，它将以一个有趣的方式显示。例如，西班牙语中的口音看起来很滑稽，东方语言（即韩语）中的字符看起来很有趣。我很确定我需要做一些编码工作，以便所有语言显示正确。

I am getting a string from a third party program that I don't control. My piece of the code outputs this in HTML. This works fine in English, but in other languages it will show in a funny way. For example, accents in Spanish look funny and characters in eastern languages (i.e. korean) will look very funny. I am pretty sure I need to do some encoding work so that all languages display correctly.

我对编码的理解是有点差，所以在发布真正的问题，我直觉地认为它是：我如何编码为UTF-8在C＃，我想通过发布更简单的问题，得到更多的理解。

My understanding of encoding is kind of poor, so before posting the real question, which I intuitively think it is: "How do I encode this to UTF-8 in C#", I would like to get more understanding on the matter by posting simpler questions.

我的问题是：我如何知道我的输入字符串有哪种类型的编码？在西班牙语中，得到口音：Acción，而不是Acción。这是ANSI还是我要处理的？

My question here is: How do I know which type of encoding does my input string has? In Spanish, it looks like this when I get an accent: "Acción", instead of "Acción". Is this ANSI or what am I dealing with?

提前多谢！

推荐答案

我得到一个重音：Acción

I get an accent: "Acción"

是一个死的救恩。重要资本A字符具有字符代码0xC0及以上。它通常是一个双字节utf-8编码字符的第一个字节。 óglyph是代码点U + 00F3，它的utf-8编码是0xC3 + 0xB3。哪些是Ã和³的码点

The presence of the à character is a dead give-away. Accented capital A characters have character code 0xC0 and up. Which is often the first byte in a two-byte utf-8 encoded character. The ó glyph is codepoint U+00F3, the utf-8 encoding for it is 0xC3 + 0xB3. Which are the codepoints for à and ³

这些字符串以utf-8编码，但是您正在使用8位编码读取它，例如Encoding.Default

The strings are encoded in utf-8 but you are reading it with an 8-bit encoding like Encoding.Default
