Download a text file directly into a string variable. Lua

-- This example requires the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

-- Connect and login to the FTP server.

    return
end

-- Download the contents of the remote file into a string variable.

-- The GetRemoteFileTextData method assumes the remote file contains ANSI chars.
-- To download text files containing non-ANSI text, such as utf-8, call GetRemoteFileTextC
-- instead. (see below)

    print(ftp.last_error_text)

end

-- To download a remote text file containing utf-8 chars,
-- call GetRemoteFileTextC and pass "utf-8" for the 2nd arg.  This tells
-- Chilkat to interpret the incoming bytes according to the utf-8 character encoding.
