Why dec to string conversion not working correctly on android?

I am making an android app which parses XML. Since XML data contains HTML hexes (&#<dec value>), I need to convert them and then show them in my app. When I am passing 8217 to my code, it returns me some chinese/japanese (I'm not sure) character. Here is my code.

public char decToChar(String dec){
    Int decimal = Integer.parseInt(dec, 16);
    return (char)decimal;
}

I am passing value '8217' to this method and it returns chinese character instead of '.

Do anyone have any idea why its not working?

You can use StringEscapeUtils.unescapeHtml4 to unescape an entity:

System.out.println(StringEscapeUtils.unescapeHtml4("&#8217;"));

Should show you the expected character ’

what are you expecting? You are probably correctly parsing the hex-value to 33303. But since you are casting it to (char) you generate a meaningless value. This is not a conversion to a character.

I would advice you to use apache commons if you can. StringEscapeUtils will do the trick.
