如何使用「UTF-8 转 Data URI」？How do I use the Convert UTF-8 to Data URI tool?
在「UTF-8 转 Data URI」中，把内容粘贴或输入到上方输入框，按需设置「MIME」，结果会实时显示在下方，点击「复制结果」即可复制。例如输入「Hi」，得到「data:text/plain;charset=utf-8,Hi」。In the Convert UTF-8 to Data URI: Paste or type into the input box, adjust "MIME"; the result appears below instantly — click "Copy result" to copy it. Example: "Hi" → "data:text/plain;charset=utf-8,Hi".
会带 charset 吗？Is the charset included?
会。百分号形式和 Base64 形式都会写上 ;charset=utf-8，例如 data:text/plain;charset=utf-8;base64,5Lit5paH，这样浏览器不会把中文按 US-ASCII 读成乱码。Yes. Both the percent form and the Base64 form include ;charset=utf-8, for example data:text/plain;charset=utf-8;base64,5Lit5paH, so browsers do not read the text as US-ASCII.
MIME 类型可以填什么？What can I put in the MIME field?
填「类型/子类型」，如 text/plain、text/html、text/csv、application/json；不要加参数（charset 会自动加上）。格式不对会报错；留空时用 text/plain 并给出提示；非文本类型（如 image/png）可以用，但会提示这里装的是文字。Use type/subtype, such as text/plain, text/html, text/csv or application/json, without parameters (the charset is added for you). An invalid value is an error; an empty field uses text/plain with a note; a non-text type such as image/png is allowed, with a note that the URI holds text.
输入和输出是什么样的？What does the input and output look like?
例如在「UTF-8 转 Data URI」中输入 Hi，输出为：data:text/plain;charset=utf-8,Hi。For example, the Convert UTF-8 to Data URI turns the input Hi into: data:text/plain;charset=utf-8,Hi.
有哪些选项可以调整？What options can I adjust?
「UTF-8 转 Data URI」的设置：「MIME」默认 text/plain；可勾选：「使用 Base64」。每次生成结果都按当前设置处理。Settings in the Convert UTF-8 to Data URI — "MIME" default text/plain; tick boxes: "Use Base64". The result always uses the current settings.
编码和加密有什么区别？Is encoding the same as encryption?
编码（如 Base64、URL 编码）可直接还原，不提供保密性；加密需要密钥。「UTF-8 转 Data URI」的处理全部在本地完成。No. Encoding (Base64, URL…) is reversible by anyone; encryption needs a key. The Convert UTF-8 to Data URI works fully offline in your browser.
