      環(huán)境：PHP內置XML-RPC的API，Apache的XML-RPC的JAVA API

      PHP下的解決方法：
      起初以為是中文字符的編碼問題，所以我就嘗試用各種編碼方式來編碼中文字符，然后交給string xmlrpc_encode_request ( string method, mixed params)函數來生成XML格式的請求，可是依然如故。百思不得其界。便操其Google 一通神搜，也沒找到解決辦法，后來我找到了http://xmlrpc-epi.sourceforge.net/這個網站。才知道，原來PHP文檔里給的xmlrpc_encode_request ( string method, mixed params)函數少了一個可選參數?。。?！正確的應該是這樣的：string xmlrpc_encode_request(string method, mixed params [, array output_options])?。utput_options的結構如下：

$output_options = array(
                       "output_type" => "xml",
                       "verbosity" => "pretty",
                       "escaping" => array("markup", "non-ascii", "non-print"),
                       "version" => "xmlrpc",
                       "encoding" => "utf-8"
                      );
or

$output_options = array("output_type" => "php");

原文說明如下：

output_type: return data as either php native data types or xml encoded. ifphp is used, then the other values are ignored. default = xml

verbosity: determine compactness of generated xml. options are no_white_space, newlines_only, and pretty. default = pretty

escaping: determine how/whether to escape certain characters. 1 or more values are allowed. If multiple, they need to be specified as a sub-array. options are: cdata, non-ascii, non-print, and markup.default = non-ascii, non-print, markup

version: version of xml vocabulary to use. currently, three are supported: xmlrpc, soap 1.1, and simple. The keyword auto is also recognized to mean respond in whichever version the request came in. default = auto (when applicable), xmlrpc

encoding: the encoding that the data is in. Since PHP defaults to iso-8859-1 you will usually want to use that. Change it if you know what you are doing. default=iso-8859-1

經過測試關鍵是在"escaping" => array("markup")這個值上，將第三個參數傳入如下值就可以解決問題了：

$output_options = array(
                       "output_type" => "xml",
                       "verbosity" => "pretty",
                       "escaping" => array("markup"),
                       "version" => "xmlrpc",
                       "encoding" => "utf-8"
                      );
