I should have thought of that. Line endings are always translated to/from
native unless the file is opened/written in binary, it's been that way
since MetaCard. It's a feature.

Thanks Bernd. But I finally figured out what the issue was. It seems that
unless the output file is opened binary, any attempt to wrote to a file
using any of the cr, lf or crlf keywords in LC will result in LC
auto-converting them to cr, because that is the Macintosh standard. What I
had to do is to use numToCodepoint() to create a variable containing ascii
characters 13 and 10 (crlf) and then use that variable to end my lines.
The way I actually figured out what the issue was, is I downloaded
Notepad++ for Windows which has the capability of showing non-printing
characters, and it does not transparently cut convert files without
informing the user, as Microsoft seems to think they have every right to
take the liberty to do.
And without putting too fine a point on it, Livecode seems to take the same
liberties. If I write lf to a file, I expect the file to contain lf and not
cr! But at least there is a way around it.

Hi Bob,
Actually I think what I need to do is figure out what the original file
encoding is, and use that when I write out the export file.
I assume that the byte order mark (BOM) is for UTF-8
To see the BOM for UTF-8 make a button and a field named "fText"
Use this script for the button
-------------------------------------------------------------
on mouseUp
local tPath, tContent, tBom, tCollect
answer file "choose"
if it is empty then exit mouseUp
put it into tPath
if the optionKey is down then
put url ("binfile:" & tPath) into tContent
delete line 2 to -1 of tContent
put textEncode(tContent, "UTF-8") into tContent
else
put url ("file:" & tPath) into tContent
delete line 2 to -1 of tContent
end if
put tContent into field "fText"
end mouseUp
-------------------------------------------------------------
and see if you see the BOM when you hold down the option key when opening
the file
If you do not use the option key there should be no BOM at the beginning of
the text and the text is automatically UTF-8 encoded
Apparently "put url ("file:" & tPath)" is also aware of the encoding of the
file since it converts it omits the BOM.
Kind regards
Bernd
