Answer 1

检查javadoc的帮助有编码/ charset的选项

我认为您应该设置-encoding这是您的来源的编码名称。

- 编码名称                指定源文件的编码名称，例如EUCJIS / SJIS。如果未指定此选项，则平台默认   使用转换器。

-charset名字                指定此文档的HTML字符集。该名称应该是IANA注册表中给出的首选MIME名称@                http://www.iana.org/assignments/character-sets。例如：
           % javadoc -charset "iso-8859-1" mypackage
         would insert the following line in the head of every generated page:

            <META http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

         This META tag is described in the HTML standard @
         http://www.w3.org/TR/REC-html40/charset.html#h-5.2.2. (4197265 and 4137321)

      Also see -encoding and -docencoding.

      -docencoding  name
         Specifies the encoding of the generated HTML files. The name should be a preferred MIME name as given in the IANA Registry @
         http://www.iana.org/assignments/character-sets. If you omit this option but use -encoding, then the encoding of the generated
HTML文件由。确定 -encoding。例如：
           % javadoc -docencoding "ISO-8859-1" mypackage

Answer 2

您的源文件看起来与系统的默认编码（Windows-1252）具有不同的字符编码。

在调用javadoc工具并指定正确的编码时，在命令行上使用-encoding option。（如果您不知道源文件的编码是什么，则必须找出答案。也许它是UTF-8。）

例如：

javadoc -encoding "UTF-8" ...

Answer 3

您的编码似乎是错误的（也许您在注释或字符串常量中使用特殊字符）。你应该看一下javadoc command。有一些字符编码参数：

encoding指定输入编码
docencoding指定输出编码
charset使javadoc包含带编码信息的元标记

javadoc发生器
