�rende: Byte Order Mark
=======================
Hello Kees,

On Monday April 14 2014 16:35, you wrote to me:

That is debateable.

Some will argue that the message contains a binary header followed by blocks of
control lnes and text. The (UTF-8) text block starts after the first block of
control lines. Golded takes that POV:

You see the byte order mark as the first three bytes of the text block.

 KE> The fact that your messages editor does not show part of the message,
 KE> does not mean, that it is not there.

It is there but the editor does not consider it part of the text.

 KE>  By the way, I would not recommend putting the BOM before the area
 KE> tag, I expect, that tossers will balk. ;)

It would indeed mess up the tossing process, but it won't happen anyway. The
AREA tag is not present at this stage. It is inserted by the tosser when
exporting and removed again when importing the messsage into the message base.

Cheers, Michiel
