问题描述：
在使用php和java操作xml-rpc的时候，如果request中包含中文字符，会被自动编码成如下样式：
欢欢 。
环境：php内置xml-rpc的api，apache的xml-rpc的java api
php下的解决方法：
起初以为是中文字符的编码问题，所以我就尝试用各种编码方式来编码中文字符，然后交给string xmlrpc_encode_request ( string method, mixed params)函数来生成xml格式的请求，可是依然如故。百思不得其界。便操其google 一通神搜，也没找到解决办法，后来我找到了http://xmlrpc-epi.sourceforge.net/这个网站。才知道，原来php文档里给的xmlrpc_encode_request ( string method, mixed params)函数少了一个可选参数！！！！正确的应该是这样的：string xmlrpc_encode_request(string method, mixed params [, array output_options])！！output_options的结构如下：
$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");
原文说明如下：
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
经过测试关键是在"escaping" => array("markup")这个值上，将第三个参数传入如下值就可以解决问题了：
$output_options = array(
"output_type" => "xml",
"verbosity" => "pretty",
"escaping" => array("markup"),
"version" => "xmlrpc",
"encoding" => "utf-8"
);
找遍了apache提供的api好像也没有找到类似php那样的第三个参数，实在无奈发现他提供了一个base64的类，我便只好将所有的中文字符在client端用 base64编码，然后request到server上，然后在server端在用base64解码，哈哈～～～问题也能解决！不过不知道还有没别的更好的办法了?
谁有更好的解决方法请和我联系：
