setContentTypeCharset

public static java.lang.String setContentTypeCharset(java.lang.String contentType,
                                                     java.lang.String charset)

Given a Content-Type header value (a mime type plus an optional charset parameter) change/add the given charset. Note that in theory text/* can have other parameters (eg, text/plain and rfc-3676) but we do not handle those cases.

Parameters:

contentType - a mime media-type plus an optional charset parameter.

charset - the iana registered charset (eg ISO-8859-1) to add.

Returns:

a media-type plus an associated charset parameter.

Parameters:

contentType -

Returns:

the charset associated with this media-type, or null.
