Summary: Wrong handling of non-latin1 characters in HTTP
request parameters.
Product: Tomcat 7
Version: 7.0.2
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Catalina

Example app
It seems that after URL-decoding a parameter value that value is treated as a
string in some 1-byte charset, but not as a string encoded with a charset
specified by http's request character encoding.
To reproduce, run an attached application. The start page has a link to a
test servlet and passes it a parameter that has non-latin1 characters. The test
servlet, in turn, creates two files in the current working directory into which
it prints the following two values:
1. req.getParameter("parameter")
2. new String(req.getParameter("parameter").getBytes("latin1"),"utf-8")
The second file contains the actual value of the parameter, while the first
one contains some junk which looks like a result of utf-8 encoding a string
that was created by treating the original utf-8 value as a string in some
1-byte charset.
The full source code for the test servlet is in
WEB-INF/classes/TestServlet.java.
