Java crawler crawled HTML content hollow lattice ( ) changed to question mark "?" The workaround

In the Java crawler, using the XPath crawl content, found that the Web page source of   all display as? (question mark), but the use of a string of replace ("?", ""), and can not be replaced, the internet looked for a bit, probably means that the question mark is not actually a question mark, is garbled, mainly due to the problem of coding.

Here's how to fix it:

// Replace " " in crawl content The question that becomes question mark is try  {        new String (Intro.getbytes (), "GBK"). Replace ('? ', '). Replace (', '). 'catch  (Exception e) {        e.printstacktrace ();}

where replace (', '), which one of the preceding spaces is the full-width space.
