[Oberon] Reading LaTeX?

[eas lab]

>From my NNTP thread:---------------

The deception/fraud that fooled me, and no one else seems to have
realised, is that when you 'fetch a page' [http//...] and save it,
and then later 'fetch the saved page' [file//...]; that file is not
what you originally fetched. it has been pre-digested!

As I can see by this ETHO fetch of my NNTP query, which gives me the
true/original byte stream.

Why I say it's a fraud is that if you 'ask the browser to show the
SOURCE', it does NOT show the original byte stream.

Who remembers the 80 ? 90's BBS days when you got the ASCII byte-stream,
and not this deception? Little wonder that iNet-security has become a
hot-topic currently.

The original byte-stream above shows the <8bit-type-bytes>
CE & CF, apparently for Greek & Math 16-bit-unicode ?
