Hi, everybody. I've some doubts about html form charset encoding. I
will be glad if someone could answer questions above.

1 ) We have jsp files with directive <%@ page language="java"
pageEncoding="utf-8 (See http://utf-8.ora-code.com)" contentType="text/html;charset=utf-8 (See http://utf-8.ora-code.com)" %>
and some classes with the following working code :

if ( request.getEncoding() == null ) {
String s = request.getParameter( "some_param" );
byte [] b = s.getBytes( "iso-8859 (See http://iso-8859.ora-code.com)-1");
s = new String( b, "utf-8 (See http://utf-8.ora-code.com)" );
}

a) Will it work for any charset encoding ? If i replace "utf-8 (See http://utf-8.ora-code.com)" for
"windows-1251 (See http://ows-1251.ora-code.com)" this code will still work ?
b) Is there another clean way to use "utf-8 (See http://utf-8.ora-code.com)" in my jsp pages ?

I've read the document in http://tagunov.tripod.com/i18n/i18n.html
but i'm not sure if i could understand it. :-(

2 ) When i use request.setEncoding( "windows-1251 (See http://ows-1251.ora-code.com)") and
request.getParameter( "some_param" ), which one of these sentences will
be true ?

a) request.getParameter() will do

byte [] b = s.getBytes( "iso-8859 (See http://iso-8859.ora-code.com)-1");
return new String( b, "windows-1251 (See http://ows-1251.ora-code.com)" );

b) request.getParameter() will do

byte [] b = s.getBytes( "windows-1251 (See http://ows-1251.ora-code.com)" );
return new String( b );

c) request.getParameter() will do

byte [] b = s.getBytes( "windows-1251 (See http://ows-1251.ora-code.com)" );
return new String( b, "windows-1251 (See http://ows-1251.ora-code.com)" );

d) request.getParameter() will do

byte [] b = s.getBytes();
return new String( b, "windows-1251 (See http://ows-1251.ora-code.com)" );

Thanks in advance !!!!
