UTF-8 Encoding

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Use Spring hessian to export hessian service that is encoded using UTF-8
2. Invoke this service using HessianClient.php will produce error string 
message due to the mismatched encoding.

I'm Using the latest 2.2 release.

when i check your source code[Hessian2Parser.php], i find your library do the 
following check.

function readUTF8Bytes($len){
    if(HessianUtils::isInternalUTF8())
        return $string;
    return utf8_decode($string);
}

so if the string is already utf8 encoded and the 
;mbstring.internal_encoding = UTF-8 in the php.ini is't correct config
or have no permission to the php.ini. the string will decode to ascii

so i add the following code to the method and it's works for me.

function readUTF8Bytes($len){
    if(HessianUtils::isInternalUTF8())
        return $string;
    if(mb_detect_encoding($string) == 'UTF-8')
        return $string;
    return utf8_decode($string);
}

Hope that it will help.

THANKS FOR YOUR GTREAT LIBRARY!!!
