「Unicode 转 ASCII（去掉重音、全角转半角、替换特殊符号）」是什么？What is the Convert Unicode to ASCII tool?

把含有 Unicode 字符的文本转换成纯 ASCII：去掉重音符号（é → e、ñ → n）、拆分连字（æ → ae、ß → ss、fi → fi），全角字母数字和标点转半角，弯引号、长破折号、省略号、特殊空格转成普通符号，© ™ € 等符号转成 (c) (TM) EUR；无法转换的字符（如汉字）可以删除、替换成 ?，或写成 \uXXXX、&#x...;、U+XXXX 转义形式。适合清理文件名、代码、URL slug 和老旧系统的数据导入，数据在本地处理。Convert text with Unicode characters into plain ASCII. Accents are removed (é → e, ñ → n), ligatures are split (æ → ae, ß → ss, fi → fi), full-width letters, digits and punctuation become half-width, curly quotes, long dashes, ellipses and special spaces become ordinary symbols, and © ™ € and similar turn into (c) (TM) EUR. Characters that can't be converted (such as Chinese) can be removed, replaced with ?, or written as \uXXXX, &#x...; or U+XXXX escapes. Great for cleaning file names, code, URL slugs and data for older systems. Processed locally.

哪些字符能转换？Which characters can be converted?

带重音或附加符号的拉丁字母（é è ê ë ñ ç ā ő 等）会去掉符号；æ œ ß ø ł 等特殊字母和 fi fl 连字会拆成对应的 ASCII 字母；全角字母、数字和标点、上标数字转成普通字符；弯引号、各种破折号、省略号、不间断空格和零宽字符被规范化；常见符号转成文字形式，例如 © → (c)、€ → EUR、→ → ->。Latin letters with accents or marks (é è ê ë ñ ç ā ő and so on) lose the marks; special letters like æ œ ß ø ł and ligatures such as fi fl become their ASCII spelling; full-width letters, digits and punctuation and superscript digits become ordinary characters; curly quotes, dashes, ellipses, non-breaking spaces and zero-width characters are normalised; and common symbols become text, e.g. © → (c), € → EUR, → → ->.

汉字、希腊字母会怎样？What happens to Chinese, Greek and other scripts?

汉字、日文、韩文、希腊字母、西里尔字母、表情等没有对应 ASCII 写法的字符属于“无法转换的字符”，可以删除、替换成 ?、保留，或写成 \u4E2D（JavaScript / JSON / Java）、中（HTML）、U+4E2D 这样的转义形式（U+ 转义后面紧跟另一个转义或 0–9、A–F 时会加一个空格隔开，避免读错）。转义后的文本是纯 ASCII，但仍保留原字符的信息，可在程序里还原。需要拼音请使用“汉字转拼音”。Chinese, Japanese, Korean, Greek, Cyrillic, emoji and anything else without an ASCII spelling count as unconvertible. They can be removed, replaced with ?, kept, or written as escapes like \u4E2D (JavaScript / JSON / Java), 中 (HTML) or U+4E2D (a U+ escape followed by another escape or by 0–9 / A–F gets a space after it, so it cannot be misread). Escaped text is pure ASCII but keeps the original characters' information so programs can restore them.

和“去除重音符号”有什么区别？How is this different from Remove Accents?

“去除重音符号”只去掉字母上的重音；本工具的目标是得到纯 ASCII 文本，还会处理连字、全角字符、标点符号、特殊空格和各种符号，并统一处理其余无法转换的字符，适合需要严格 ASCII 的场合（文件名、旧系统、网址、代码标识符）。Remove Accents only strips accent marks from letters. This tool aims for pure ASCII, so it also deals with ligatures, full-width characters, punctuation, special spaces and symbols, and handles everything else consistently — for places that need strict ASCII (file names, legacy systems, URLs, code identifiers).
