如何使用「整数写成花体 / 数学字体」？How do I use the Write Integers in Fancy Font tool?
在「整数写成花体 / 数学字体」中，把内容粘贴或输入到上方输入框，按需设置「样式」，结果会实时显示在下方，点击「复制结果」即可复制。例如输入「123」，得到「𝟏𝟐𝟑」。In the Write Integers in Fancy Font: Paste or type into the input box, adjust "Style"; the result appears below instantly — click "Copy result" to copy it. Example: "123" → "𝟏𝟐𝟑".
怎样输入多个整数？How do I enter several integers?
每行一个，或用空格、逗号、分号分隔。像 1,234,567 这样每 3 位一个逗号的写法按千位分隔读作一个数（所以 10,100 是 10100，要表示两个数请写 10 100）；也可以用下划线分组（1_000）。负号可用 -、−（U+2212）或全角 －，全角数字也能识别。小数、科学计数法（1e3）或夹杂文字会报错并指出是第几个、完整显示那个值。One per line, or separated by spaces, commas or semicolons. A value with a comma every three digits, like 1,234,567, is read as one number with thousands separators (so 10,100 is 10100; write 10 100 for two values); underscores also group digits (1_000). Minus can be a hyphen, the Unicode minus (U+2212) or the fullwidth minus, and fullwidth digits work. Decimals, scientific notation (1e3) or stray text give an error naming the position and showing the whole value.
会改变数字的值吗？Can the value change?
不会。每一位数字只是换成对应的 Unicode 字符（逐位处理，processed as text），不经过浮点计算，几十位的数也完全一致。No. Each digit is simply swapped for the matching Unicode character (processed as text), with no floating-point arithmetic, so even numbers with dozens of digits stay identical.
到处都能显示吗？Will it display everywhere?
需要支持 Unicode 数学字母数字的字体；部分旧设备可能显示方框。It needs a font that covers Mathematical Alphanumeric Symbols; some older devices may show boxes.
输入和输出是什么样的？What does the input and output look like?
例如在「整数写成花体 / 数学字体」中输入 123，输出为：𝟏𝟐𝟑。For example, the Write Integers in Fancy Font turns the input 123 into: 𝟏𝟐𝟑.
