Subject [Tomcat Wiki] Trivial Update of "FAQ/CharacterEncoding" by KonstantinKolinko
Date Sun, 28 Mar 2010 11:17:28 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Tomcat Wiki" for change notification.

The "FAQ/CharacterEncoding" page has been changed by KonstantinKolinko.
The comment on this change is: Corrected some misprints.
http://wiki.apache.org/tomcat/FAQ/CharacterEncoding?action=diff&rev1=10&rev2=11

--------------------------------------------------

   1. Set the `URIEncoding` attribute on the <Connector> element in server.xml to something
specific (e.g. `URIEncoding="UTF-8"`).
   1. Set the `useBodyEncodingForURI` attribute on the <Connector> element in server.xml
to `true`. This will cause the Connector to use the request body's encoding for GET parameters.

encoding filter or jsp page has a chance to set the encoding to UTF-8.  For more information

  ''Default encoding for GET''
  
- The character set for HTTP query strings (that's the technical term for 'GET parameters')
can be found in sections 2 and 2.1 the "URI Syntax" specification. The character set is defined
to be [[http://en.wikipedia.org/wiki/ASCII|US-ASCII]]. Any character that does not map to
US-ASCII must be encoded in some way. Section 2.1 of the URI Syntax specification says that
characters outside of US-ASCII must be encoded using `%` escape sequences: each character
is encoded as a literal `%` followed by the two hexadecimal codes which indicate its character
code. Thus, `a` (US-ASCII character code 0x97) is equivalent to `%97`. There ''is no default
encoding for URIs'' specified anywhere, which is why there is a lot of confusion when it comes
to decoding these values.

  Some notes about the character encoding of URIs:
   1. ISO-8859-1 and ASCII are compatible for character codes 0x20 to 0x7E, so they are often
used interchangeably. Most of the web uses ISO-8859-1 as the default for query strings.
