Write Text to a Remote SFTP File (Sequential)

Demonstrates the Chilkat SFtp.WriteFileText method, which encodes text using a charset and writes it at the current sequential write position of an open handle. The arguments are the handle, the charset, and the text.

Background: Chilkat tracks a write position per handle, so successive WriteFileText calls append naturally — the pattern for building a file a piece at a time, such as writing rows to a report. Opening with openOrCreate starts writing at the current end of the file. The charset determines the bytes actually stored, which matters whenever the text contains non-ASCII characters.
