「码位转 Unicode 字符」是什么？What is the Convert Code Points to Unicode tool?
把码位（U+XXXX、0x 前缀或纯数字，纯数字默认按十六进制）转成字符，拒绝代理码位和超出 U+10FFFF 的值。本地处理。Turn code points (U+XXXX, 0x prefix or bare numbers, bare numbers hex by default) into characters, rejecting surrogates and values above U+10FFFF. Processed locally.
如何使用「码位转 Unicode 字符」？How do I use the Convert Code Points to Unicode tool?
在「码位转 Unicode 字符」中，把内容粘贴或输入到上方输入框，按需设置「纯数字按」，结果会实时显示在下方，点击「复制结果」即可复制。例如输入「U+41 U+42」，得到「AB」。In the Convert Code Points to Unicode: Paste or type into the input box, adjust "Bare numbers are"; the result appears below instantly — click "Copy result" to copy it. Example: "U+41 U+42" → "AB".
可以输入哪些格式？Which formats can I enter?
U+1F600、0x1F600 和纯数字 1F600 都按十六进制读取（这是 U+ 码位的惯例）；如果要输入十进制（如 128512），把“纯数字按”改成“十进制”，此时 U+ 和 0x 仍按十六进制。以 0b 开头的按二进制读取（如 0b1000001 = A）。多个码位用空格、逗号或分号分隔。U+1F600, 0x1F600 and the bare number 1F600 are all read as hex, following the U+ convention. To enter decimal values such as 128512, set Bare numbers are to Decimal; U+ and 0x still mean hex. A 0b prefix means binary, so 0b1000001 is A. Separate several code points with spaces, commas or semicolons.
哪些码位会被拒绝？Which code points are rejected?
超过 U+10FFFF 的值，以及 U+D800–DFFF 的代理码位（它们不是字符，只在 UTF-16 里成对出现）。错误信息会引用出错的那一项并给出它是第几个。Values above U+10FFFF and the surrogates U+D800–DFFF, which are not characters and only appear in pairs inside UTF-16. The error quotes the offending entry and says which one it is.
输入和输出是什么样的？What does the input and output look like?
例如在「码位转 Unicode 字符」中输入 U+41 U+42，输出为：AB。For example, the Convert Code Points to Unicode turns the input U+41 U+42 into: AB.
