Hello Kees,

On Monday April 14 2014 18:21, you wrote to me:

That is why I mentioned "blocks of control lines and text".  There can be more than one block of each. A blocl can be as small as a single line.

But as you say: there are no rules. UTF-8 in general and the presence of a byte order marker in oparticular was not foreseen when the fidonet specs were written. so the fidonet specs do not tell us where to put it.

You say the placing in in what you say is midstream is wrong, but the Unicode standard says this:

So... placing a BOM in the middle of the data stream is not forbidden.

A decent viewer should not display it. If Maurice sees it, it is his viewer that is at fault.

It does not make it incorrect either. The Unicode standard allows it.

We can argue if the presence of a BOM is desirable in the Fidonet environment. But unless we make a rule to outlaw it, it is allowed by all the standards that apply.


Cheers, Michiel
