> Hello.
> I am not sure if this is a bug in xerces or me not using xerces well.
> This is my code:
> <code>
> #include <string>
> #include <iostream>
> #include <xercesc/dom/DOM.hpp>
> #include <xercesc/dom/DOMException.hpp>
> #include <xercesc/dom/DOMImplementationRegistry.hpp>
> #include <xercesc/framework/MemBufInputSource.hpp>
> #include <xercesc/parsers/XercesDOMParser.hpp>
> #include <xercesc/util/PlatformUtils.hpp>
> #include <xercesc/util/XMLString.hpp>
> using namespace std;
> using namespace XERCES_CPP_NAMESPACE;
> void replaceSpecialCharactersXML(std::string &s)
> {
>     string cp;
>     unsigned int i;
>     cp.reserve(s.size()*2);
>     for (i = 0; i < s.size(); i++)
>     {
>         const unsigned char c = s[i];
>         if ((c < 32 && c != '\012' && c != '\015') || c > 127)
>         {
>             char buffer[10000];
>             sprintf(buffer, "&#x%02x;", c);
>             cp += buffer;
>         }
>         else
>         {
>             cp += c;
>         }
>     }
>     s = cp;
> }
> int main()
> {
>     XMLPlatformUtils::Initialize();
>     string aString0 ("This will crash ££££ ...");
>     XMLCh*   fUnicodeForm =  XMLString::transcode(aString0.c_str());
>     char *pMsg = XMLString::transcode(fUnicodeForm);
>     string res(pMsg);
>     replaceSpecialCharactersXML(res);
>     cout << aString0 << " -> " << pMsg << " -> " << res << endl;
>     return 0;
> }
> </code>
> When I compile and run, I have that output:
> <output>
> sh$ ./testxerces                                                                                                                                        
> This will crash ££££ ... -> This will crash  ... -> This will crash &#x1a;&#x1a;&#x1a;&#x1a; ...
> </output>
> When I transcode the £ sign to XMLCh, then transcode it back to a char*, it is transformed to 0x1a.
> Is it a real bug, or is it just me missing something ?
> Regards,
> Jean-Baptiste
