如何使用「生成码位范围表」？How do I use the Generate Unicode Range tool?
在「生成码位范围表」中，把内容粘贴或输入到上方输入框，按需设置「起始」、「结束」、「最多行数」，结果会实时显示在下方，点击「复制结果」即可复制。In the Generate Unicode Range: Paste or type into the input box, adjust "From", "To", "Max rows"; the result appears below instantly — click "Copy result" to copy it.
控制字符和空白码位怎么显示？How are control characters and empty code points shown?
换行、制表等控制字符显示为转义写法（如 \u0007、\u000A）并标注“控制字符”，不会打乱表格；未分配的码位标“未分配”，U+FFFE、U+FDD0 这类非字符标“非字符”；代理码位 U+D800–DFFF 跳过。Control characters such as line feed and tab are shown as escapes (for example \u0007 and \u000A) marked control, so they never break the table. Unassigned code points are marked unassigned, noncharacters such as U+FFFE and U+FDD0 are marked noncharacter, and the surrogates U+D800–DFFF are skipped.
范围太大怎么办？What if the range is very large?
只列出前“最多行数”个（默认 256，最多 5000），并在结果下方提示范围内一共有多少个码位。Only the first Max rows (256 by default, up to 5000) are listed, and a note below the result gives the total number of code points in the range.
会上传文本吗？Is my text uploaded?
不会，全部在浏览器里用 JavaScript 处理，文本不会离开你的设备。No. Everything runs in your browser with JavaScript and the text never leaves your device.
输入和输出是什么样的？What does the input and output look like?
例如在「生成码位范围表」中输入 x，「起始」设为 U+41，「结束」设为 U+43，输出为：U+0041 ⇥ A ⏎ U+0042 ⇥ B ⏎ U+0043 ⇥ C（⏎ 表示换行，⇥ 表示制表符）。For example, the Generate Unicode Range turns the input x, "From" set to U+41, "To" set to U+43 into: U+0041 ⇥ A ⏎ U+0042 ⇥ B ⏎ U+0043 ⇥ C (⏎ marks a line break, ⇥ marks a tab).
有哪些选项可以调整？What options can I adjust?
「生成码位范围表」的设置：「起始」默认 U+41；「结束」默认 U+4A；「最多行数」默认 256。每次生成结果都按当前设置处理。Settings in the Generate Unicode Range — "From" default U+41; "To" default U+4A; "Max rows" default 256. The result always uses the current settings.
