check the help of javadoc there are options for encoding/charset

I think you should set the -encoding which is the encoding name of your source.

-encoding name
Specifies the encoding name of the source files, such as EUCJIS/SJIS. If this option is not specified, the platform default
converter is used.

-charset name
Specifies the HTML character set for this document. The name should be a preferred MIME name as given in the IANA Registry @
http://www.iana.org/assignments/character-sets. For example:

           % 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 files is determined by
-encoding. Example:

           % javadoc -docencoding "ISO-8859-1" mypackage
