宽度是怎么算的？How is the width measured?
默认按东亚宽度（East Asian Width）算显示列：中日韩文字、全角字符和 Emoji 各占 2 列，组合附加符和零宽字符占 0 列，其余字符占 1 列，适合等宽字体。选“字素”则每个用户看到的字符都算 1。By default display columns follow East Asian Width: CJK characters, fullwidth forms and emoji take 2 columns, combining marks and zero-width characters take 0, and everything else takes 1, which suits monospaced fonts. Choose Graphemes to count every user-perceived character as 1.
多行文本怎么处理？What about several lines?
每一行都单独居中，空行保持为空；比目标宽度更宽的行原样保留，并在结果下方提示有几行。Every line is centred on its own and blank lines stay blank. Lines wider than the target are left unchanged and a note below the result says how many.
全角空格怎么用？How does the ideographic space option work?
勾选后用全角空格（占 2 列）补齐，剩下的奇数列用一个普通空格补上；按字素模型时每个全角空格算 1。The padding uses ideographic spaces (2 columns each), with one ordinary space for an odd remaining column; under the Graphemes model each ideographic space counts as 1.
