No, I'm afraid the line break callback is not what you want here.
Besides, that callback is no longer supported in version 3.0.

When you hit the return key on a Macintosh keyboard, the OS
generates a CR (ASCII 13), but your UNIX web server expects
a LF (ASCII 10) instead.  So my guess is that you simply need
to map CRs to LFs upon saving the text into a file.
Using WEFind/WEPut for this conversion is definitely inefficient.
You'll be better off using a simple loop like this:

    void MapCRToLF(char * ioText, ByteCount inTextSize)
    {
        for (ByteCount index = 0; index < inTextSize; ++index)
        {
            if (ioText[index] == 13)
            {
                ioText[index] = 10;
            }
        }
    }

    Handle MyExtractUNIXCompatibleText(WEReference inWE)
    {
        Handle  hText = NewHandle(0);

        WEStreamRange(0, 0x7fffffff, 'TEXT', 0, hText, inWE);
        MapCRToLF(*hText, GetHandleSize(hText));
        return hText;
    }


Hope this helps,

They want to turn it into a one-way flow that they have entirely
monetized. I look at the collective human mind as a kind of
ecosystem. They want to clear cut it. They want to go into the
rainforest of human thought and mow the thing down.
