You can use
the client.encoding.override=UTF-8 JVM argument
to configure an application server for UCS Transformation Format.
This format enables an application server to handle most character
encodings, including specialized mathematical and technical symbols.
About this task
The client.encoding.override=UTF-8
argument is provided for
backwards compatibility. You should only specify this argument if
you require multiple language encoding support in the administrative
console and there is no other way for you to set the request character
encoding required to parse post and query strings.
Before configuring
an application server for UCS Transformation Format, you should try
to either:
- Explicitly set the ServletRequest Encoding inside
of the JSP or
Servlet that is receiving the POST and or query string data, which
is the preferred J2EE solution, or
- Enable the autoRequestEncoding,
option, which uses the client's
browser settings to determine the appropriate character encoding.
Older browsers might not support this option.
Avoid trouble: If the client.encoding.override=UTF-8
JVM argument is specified, the autoRequestEncoding option does not
work even if it is enabled. Therefore, when an application server
receives a client request, it checks to see if the charset option
is set on the content type header of the request:
- If
it is set, the application server uses the content type header
for character encoding.
- If it is not set, the application
server uses the character encoding
that is specified for the default.client.encoding system property.
- If neither charset nor the default.client.encoding system property
is set, the application server uses the ISO-8859-1 character set.
The application server never checks for an Accept-Language
header. However, if the autoRequestEncoding option is working, the
application server checks for an Accept-Language header before checking
to see if a character encoding is specified for the default.client.encoding
system property.
