default character encoding of the request or response body:
If a character encoding is not specified, the Servlet specification requires that an encoding of ISO-8859-1 is used.
For JSP pages,The request character encoding handling is the same,for JSP pages in standard syntax the default response charset is the usual ISO-8859-1, but for the ones in XML syntax it is UTF-8.
Default encoding for GET
Many browsers are starting to offer (default) options of encoding URIs using UTF-8 instead of ISO-8859-1.
HTML 4.0 recommends the use of UTF-8 to encode the query string.
Default Encoding for POST
ISO-8859-1 is defined as the default character set for HTTP request and response bodies in the servlet specification
