Convert a Text File from utf-8 to Windows-1252

Convert a text file from one character encoding to another. PowerBuilder

integer li_rc
long li_Success
oleobject loo_Sb

li_Success = 0

//  It's really simple:  Just load from one charset, save using another.

loo_Sb = create oleobject
li_rc = loo_Sb.ConnectToNewObject("Chilkat.StringBuilder")
if li_rc < 0 then
    destroy loo_Sb
    MessageBox("Error","Connecting to COM object failed")
    return
end if

//  In this case, my test file has some norwegian chars in the utf-8 encoding
li_Success = loo_Sb.LoadFile("qa_data/txt/norwegian_chars.txt","utf-8")

//  We could just as well write over the file we just read in.
//  (But I don't want to do that for my example..)
li_Success = loo_Sb.WriteFile("qa_output/norwegian_chars.txt","windows-1252",0)

//  Note:  Windows-1252 is a 1-byte per char encoding, which means it's only capable of representing
//  those chars in Western European languages.   See https://en.wikipedia.org/wiki/Windows-1252
//  
//  utf-8 is an encoding that can handle chars in any language, including Chinese, Korean, Japanese, Arabic, Hebrew, Greek, etc.
//  If a text file contains chars in these other languages, obviously it cannot be converted to windows-1252 because
//  there are only 256 chars that can possibly be represented in a 1-byte per char encoding.
