Hi, there, when I try to fetch html code and plain text of a URL, the content becomes garbled.
I think some where was not as good as your expected. When gzip was disabled at AcceptEncoding Header, everythin goes fine.
When gizp was enabled, com.gargoylesoftware.htmlunit.html.parser.neko.HtmlUnitNekoHtmlParser.parse() will be call and the charset of the page will be set to ISO_8859_1 in the HtmlUnitNekoHtmlParser.java file at line 181:
charset = StandardCharsets.ISO_8859_1;

Here is the code:

import com.gargoylesoftware.htmlunit.BrowserVersion;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlPage;
import java.io.IOException;
import java.net.MalformedURLException;
public class HTest {
    public static void main(String[] args) {
        final BrowserVersion browser =
                new BrowserVersion.BrowserVersionBuilder(BrowserVersion.FIREFOX)
                        // uncomment this or change "deflate" to "br" to get right charset of UTF-8 which declared in html source code at line 36: <meta charset="utf-8" />
                        //.setAcceptEncodingHeader("deflate")
                        .build();
        try (final WebClient webClient = new WebClient(browser)) {
            webClient.getOptions().setThrowExceptionOnScriptError(false);
            try {
                 String url="http://www.jj.gov.cn/art/2021/8/19/art_1229539289_59057787.html";
                final HtmlPage page = webClient.getPage(url);
                final String pageAsXml = page.asXml();
                System.out.println(pageAsXml);
                final String pageAsText = page.asNormalizedText();
                System.out.println(pageAsText);
            } catch (MalformedURLException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}
