    - #### getMetadataCharset

          public String getMetadataCharset()

      The character set used to encode JAR metadata like file names. Defaults to UTF-8. You can change this property but it is not recommended as JVMs expect JAR metadata to be encoded using UTF-8
      Overrides:
        `getMetadataCharset` in class `Zip`
      Returns:
        the character set used to encode JAR metadata like file names
      Since:
        2.14

    - #### setMetadataCharset

          public void setMetadataCharset​(String metadataCharset)

      The character set used to encode JAR metadata like file names. Defaults to UTF-8. You can change this property but it is not recommended as JVMs expect JAR metadata to be encoded using UTF-8
      Overrides:
        `setMetadataCharset` in class `Zip`
      Parameters:
        `metadataCharset` - the character set used to encode JAR metadata like file names
      Since:
        2.14

    - #### getManifestContentCharset

          @Input
          public String getManifestContentCharset()

      The character set used to encode the manifest content. Defaults to UTF-8. You can change this property but it is not recommended as JVMs expect manifests content to be encoded using UTF-8.
      Returns:
        the character set used to encode the manifest content
      Since:
        2.14

    - #### setManifestContentCharset

          public void setManifestContentCharset​(String manifestContentCharset)

      The character set used to encode the manifest content.
      Parameters:
        `manifestContentCharset` - the character set used to encode the manifest content
      Since:
        2.14
      See Also:
        `getManifestContentCharset()`

    - #### getManifest

          @Internal
          public Manifest getManifest()
