Losing UTF-8 characters at the end of a string

[Matthew Boulter]

Hi all, I just wanted some guidance of where to expend my investigation effort
into this topic.

 

I have a MySQL database that contains names of some Polish tram stops that I am 
extracting and encoding as WBXML for transmission.

Now I find when I get them from the database all is good until I get to the 
part where
I'm at our DomToWbxml task.

 

I find if the string has a Polish character it loses a character from the end 
of the string, 
if there are two it loses two and so on.

I read Xerces is UTF-16? If so am I losing something (other than my mind) going 
back to UTF-8 ?

 

Any help is greatly appreciated.

Regards, 

Matthew

 

 

Below is an extract from a logfile:

 

Next stop name == Łukowa

In operator () - node_line.c_str() == 
40,676,51.71878333,19.43771667,busstop,620,5,80,25,10,exit,none,,,never, Łukowa

DomToWbxml::Process

AddContent - 
c_str(40,676,51.71878333,19.43771667,busstop,620,5,80,25,10,exit,none,,,never, 
Łukow)

AddContent - none 
(40,676,51.71878333,19.43771667,busstop,620,5,80,25,10,exit,none,,,never, Łukow)

        DOM_Element node_element = vss_doc->createElement("node");

        cout << "In operator () - node_line.c_str() == " << node_line.c_str() 
<< endl; 

        node_element.appendChild(vss_doc->createTextNode(node_line.c_str()));

        service_element.appendChild(node_element);

There is obviously a lot of code not shown, but I believe the above is where 
the issue is, 
or perhaps it is going into the WBXML parser

bool WbxmlParser::convert_to_wbxml(const DOM_Node & node)

{

  string node_name         = transcode( node.getNodeName() );

  string node_value         = transcode( node.getNodeValue() );

 

Using ...

 

string WbxmlParser::transcode(const DOMString& xstr)

{

  if (xstr == 0)

    return string();

    

  char * cstr = xstr.transcode();

  string result(cstr);

  delete [] cstr;

  return result;

}
