A coworker of mine created a basic contact-us type form, which is mangling accented characters (è, é, à, etc). We're using KonaKart a Java e-commerce platform on Struts 1.
I've narrowed the issue down to the data coming in through the HttpServletRequest object. Comparing a similar (properly functioning) form, I noticed that on the old form the request object's Character Encoding (request.getCharacterEncoding()
) is returned as "UTF-8", but on the new form it is coming back as NULL, and the text coming out of request.getParameter()
is already mangled.
Aside from that, I haven't found any significant differences between the known-good form, and the new-and-broken form.
Things I've ruled out:
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<%@page contentType="text/html;charset=UTF-8" language="java" %>
tagIf I convert them from ISO-8859-1 to UTF-8, it works great, but I would much rather figure out the core issue.
eg: new String(request.getParameter("firstName").getBytes("ISO-8859-1"),"UTF8")
Any suggestions are welcome, I'm all out of ideas.
Modern browsers usually don't supply the character encoding in the HTTP request Content-Type
header. It's in case of HTML form based applications however the same character encoding as specified in the Content-Type
header of the initial HTTP response serving the page with the form. You need to explicitly set the request character encoding to the same encoding yourself, which is in your case thus UTF-8.
request.setCharacterEncoding("UTF-8");
Do this before any request parameter is been retrieved from the request (otherwise it's too late; the server platform default encoding would then be used to parse the parameters, which is indeed often ISO-8859-1). A servlet filter which is mapped on /*
is a perfect place for this.
