upload file name with special characters using libcurl

Question

Tried to copy the file HU98373+TRRepr#o4_201702061135_34 from local system to remote destination using curl FTP.

In remote system it has created file with HU98373+TRRepr but not HU98373+TRRepr#o4_201702061135_34. I don't know why it is not considering '#' character

Please check the below code.

remoteFileUrl = ftp://IPADRESS/HOME/HU98373+TRRepr#o4_201702061135_34.tmp/C20170206.1135-20170206.1140

curl_easy_setopt(m_CurlSessionHandle, CURLOPT_URL, remoteFileUrl);
                        curl_easy_setopt(m_CurlSessionHandle, CURLOPT_UPLOAD, ON);

                        // Set the input local file handle
                        curl_easy_setopt(m_CurlSessionHandle, CURLOPT_READDATA, localFileHandle);

                        // Set on/off all wanted options
                        // Enable ftp data connection
                        curl_easy_setopt(m_CurlSessionHandle, CURLOPT_NOBODY, OFF);

                        // Create missing directory into FTP path
                        curl_easy_setopt(m_CurlSessionHandle, CURLOPT_FTP_CREATE_MISSING_DIRS , ON) ;

                        // Set the progress function, in oder to check the stop transfer request
                        curl_easy_setopt(m_CurlSessionHandle, CURLOPT_NOPROGRESS, OFF);
                        curl_easy_setopt(m_CurlSessionHandle, CURLOPT_PROGRESSFUNCTION, progressCb);
                        curl_easy_setopt(m_CurlSessionHandle, CURLOPT_PROGRESSDATA, this);

                        CURLcode curlOperationResult = curl_easy_perform(m_CurlSessionHandle);

Can any one help me on this

A URL is composed by the following parts:

 scheme:[//[user:password@]host[:port]][/]path[?query][#fragment]

The characeter # indicates the URL fragment. You must URL encode the # character so that it is not interpreted as a fragment separator.

Once encoded, the server will parse the URL as expected and the correct file name will be generated.

The following question displayes how to do this in C++:
