There is a monumental gap between "items encoded ... is if [they] were
characters" and actual characters. This gap is the gap between Unicode and not

Lots of things are interchanged. Machine code is interchanged, Scalable Vector
Graphics are interchanged, executables are interchanged. None of these are
plain text. They should not be interpreted as plain text. They should not be
displayed as plain text, except for providing a way for those who understand
the "text" as merely a representation of bytes of data that have a non-plain
text meaning, so they can check the data. Object code is not Unicode, it is

There is not difference between a virtual machine code and a physical machine
code toa CHARACTER encoding standard. The fact that it has a high level
language style means nothing, absolutely nothing. C code is C code, whether it
is encoded as ASCII, Unicode, ISCII, Big 5, Shift-JIS, or anything else. The
details of object code are immaterial to it being fundamentally a form of
machine language, not a character.

Every writing system was invented.

No. Unicode encodes plain text. Period. Emoji are no different. They are
exchanged as plain text, and act as plain text. They were not encoded before
they were exchanged as plain text, they were only encoded ONCE they were used
as plain text. The key word here, and everywhere else, is "Plain text". If
it's not Plain text, it is not, has never been, and never will be germaine.

You know perfectly well what it means, seeing as you speak native, colloquial
English. You may think it's cute, but the people who have responded to you are
serious people who have dedicated their lives to addressing the real issues of
globalization, and it is both disrespectful and counterproductive to make
comments like this.

Which is the single most important evidence to say that this is NOT plain
text, and is completely, totally, and undeniably not Unicode.

The people who have responded to you have immeasurable experience with the
Unicode Technical Committee. They are telling you EXACTLY what will be said in
a UTC meeting. There is no subterfuge. They aren't hazing the newbie. This is
the knowledge of experts who know the Standard inside and out, because they
helped write it. Many of the people on this list actually ARE members of the
UTC, and if they disagreed in the slightest, they would instantly chime in. No
one is coming to your side and saying "there is a small chance that this could

Emoji were not created, then suggested to Unicode so they'd be interchanged:
they were created and promulgated, as plain text - not as if they were plain
text, but actually as plain text - and then encoded in Unicode. If you are
pinning your hopes on Emoji as a precedent, you are sadly unaware of even the
most basic tenets of the Standard.

Actually, it is. Whether you wish to accept it is the only undecided matter.

Emoticons (as emoji) are exchanged as plain text. The only consideration that
changed was whether they should be considered as markup or not. Eventually, it
became clear that they no longer do classify as markup, but as plain text.
This was not a change inpolicy, it was a development in evidence.

Planes 15 and 16 are Private Use planes. Nobody cares what you do there.
That's what they're for. The only thing that Unicode has to say about them is
that they are for Private Use, and public use by private agreement. Just
because there are no CURRENT plans for a plane does not mean they are open for
you to do whatever the heck you want, just as you shouldn't use the empty
spots in the Greek block. Reserved means "don't do anything here". If you want
to fulfill your craziest desires, like writing in Klingon pIqaD, use the
Private Use areas.
