Hello I’m building a Spring MVC web application that runs on Tomcat 6.0.20 and JDK 1.6.0_19. When I send some special characters through an HTML form some of them are stored as question marks ?
For example these symbols are stored correctly: €, á, é, í, ‰, etc
But some symbols are replaced with ? like: ₤, ♪, ☺
MySQL tables charset is utf-8. My jsp also use utf-8
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
I have included org.springframework.web.filter.CharacterEncodingFilter in web.xml as suggested here
When I debug the POST request when sending 3 characters €a₤ with firebug I get: %E2%82%ACa%E2%82%A4 which is correct since E2 82 AC is the code for € and E2 82 A4 is the code for ₤ but ₤ is stored as ? in the database.
When I save ₤ directly into the database it is displayed correctly in the webpage.
How can I fix this?
There are several areas where you need to check that character encoding is being correctly done as some default to UTF-8 and others do not (for example, iso-8859-1). Check:
It’s a pain in the neck to have to check all of this stuff, but someone’s gotta do it. I recommend setting everything to UTF-8 as that is generally what people agree on
To me it sounds like the JVM or your JDBC driver could be the source of the problem
