Character encoding across Web application contexts

Question

          If I submit an HTTP request encoded in SHIFT-JIS across Web application contexts,
          the characters seem to get mangled. Do I need to do anything special to pass request
          objects that are encoded in SHIFT-JIS to another context.
          

Answer 1

a. EUC-JP
EUC is Extended Unix Code.
<META HTTP-EQUIV="Content-Type" CONTENT="text/html;
charset=x-euc-jp">x-euc-jp should be EUC-JP. You use x- for non-registered
encoding names with IANA.
b. JIS
Japanese Industrial Standard
<META HTTP-EQUIV="Content-Type" CONTENT="text/html;
charset=iso-2022-jp">To be precise, JIS means nothing. JIS has many standards.
It is an ISO-2022 encoding applied to JIS code sets.
c. Shift_JIS
Microsoft's Japanese encoding method loosly based on
JIS.
<META HTTP-EQUIV="Content-Type" CONTENT="text/html;
charset=x-sjis">Use "charset=Shift_JIS" in most cases.

d. UTF-8You use charset=UTF-8.
- Which one of the above 4 I should use? Either one is fine as long as you include the meta tag
in HTML. If you want to support older generation of
browsers, then skip UTF-8. If you target i-mode
phone browser, use Shift_JIS.
- Do I have to worry about the encoding of the
Japanese data being entered by user in the input
fields in the HTML form?Yes. Use the same encoding as the encoding of the form.
Make sure to call response.setEncoding to set the
enxoding for the parameter processing.
- What should be encoding of the content of html
output generated by the JSP?Use contentType tag in page directive.
