会检查哪些问题？What does it check?
双向控制符（U+202A–202E、2066–2069、200E/200F、061C）和零宽字符（U+200B–200D、2060、FEFF），都给出字符位置；全角字母数字和数学字母数字符号；一个字素上 3 个以上的组合符（Zalgo）；以及在同一个单词里混用文字（如拉丁字母夹西里尔或希腊字母）。最后给出把形近字换成拉丁字母后的“看起来像”文本。Bidi controls (U+202A–202E, 2066–2069, 200E/200F, 061C) and zero-width characters (U+200B–200D, 2060, FEFF), each with its position; fullwidth letters and digits and mathematical alphanumeric symbols; three or more combining marks on one grapheme (Zalgo); and words that mix scripts, such as Latin with Cyrillic or Greek letters. It also shows what the text looks like with the lookalikes replaced by Latin letters.
中文、日文、韩文会被误报吗？Will Chinese, Japanese or Korean be flagged?
不会。混用判断按 UTS #39 的“高度限制”规则：汉字+平假名+片假名（日文）、汉字+注音、汉字+韩文，以及它们和拉丁字母的组合都算正常；标点、数字等通用字符不计入。表情序列里的零宽连接符（ZWJ）也不报。No. Script mixing follows the UTS #39 Highly Restrictive rule: Han with Hiragana and Katakana (Japanese), Han with Bopomofo, and Han with Hangul, each optionally with Latin, are all normal, and common characters such as punctuation and digits are ignored. Zero-width joiners inside emoji sequences are not reported either.
结果可靠吗？Is the result authoritative?
这是快速提示：形近字表只内置了常见的西里尔、希腊字母等，全角和数学字母用 NFKC 规范化识别，不能替代完整的 Unicode 混淆检测或安全产品。It is a quick hint. The lookalike table only covers common Cyrillic and Greek letters and similar, and fullwidth and mathematical letters are recognised through NFKC normalisation, so it does not replace full Unicode confusable detection or a security product.
