(Unicode C) SCP Upload Contents of String to Remote File

Demonstrates how to upload the contents of a string variable using the SCP protocol (Secure Copy Protocol over SSH). The text is uploaded to a file in specific remote directory. If the file did not already exist, it is created. If it already existed, it is overwritten.
