「生成 Unicode 分数」是什么？What is the Create Unicode Fractions tool?
把 a/b 形式的分数转成 Unicode 横线分数（若有预组合字符则用之，否则用下标/上标）。本地处理。Turn a/b fractions into Unicode vulgar fractions when available, else superscript/subscript form. Processed locally.
如何使用「生成 Unicode 分数」？How do I use the Create Unicode Fractions tool?
在「生成 Unicode 分数」中，把内容粘贴或输入到上方输入框，结果会实时显示在下方，点击「复制结果」即可复制。例如输入「1/2」，得到「½」。In the Create Unicode Fractions: Paste or type into the input box; the result appears below instantly — click "Copy result" to copy it. Example: "1/2" → "½".
没有预组合字符时？When no precomposed character?
用上标数字 + ⁄ + 下标数字拼出。Uses superscript digits + ⁄ + subscript digits.
分母为 0 或负数会怎样？结果精确吗？What about a zero or negative denominator? Is it exact?
分母为 0（如 1/0、0/0）会报错并指出是第几行；负分母会把负号移到分子（1/-2 → ⁻¹⁄₂）。转换是纯文本的逐字替换，不做任何数值计算，所以多长的数字都原样保留，分数也不会被约分（2/4 仍是 ²⁄₄）。空行会原样保留。A zero denominator (1/0, 0/0) gives an error naming the line; a negative denominator has its sign moved to the numerator (1/-2 → ⁻¹⁄₂). The conversion is processed as text, character by character, with no arithmetic, so long numbers are kept exactly and fractions are not reduced (2/4 stays ²⁄₄). Blank lines are kept.
输入和输出是什么样的？What does the input and output look like?
例如在「生成 Unicode 分数」中输入 1/2，输出为：½。For example, the Create Unicode Fractions turns the input 1/2 into: ½.
