 characters I think you were referring to (poke around the directory at

I am not proposing to encode all terminal function indicators in Unicode.

Else it would mean that we could as well standardize of those many
icons found in toolbars of GUI applications. If these symbols appear
in printed documentations, they are still snapshots of icons used in
a particular program or device, and not intended to be part of
interchanged documents...

Even today we don't need to encode icons in plain text to make
program documentations: we use images instead, even if they cannot
be exhibited in plain text documents. Our modern online documentation
uses HTML or PDF or .DOC with other embedded graphics in various
(bitmap or vectorial) formats.

Hi Philippe!

  When dealing with protocol specifications, there's often a need for
 characters like these, too, since hex byte pictures are 
 unambiguous. I have
 a DEC dumb terminal around here somewhere which also uses them when
 debugging control characters.
 
  I suppose you could argue it's purely a formatting issue, though.
 
 If you've got some technical documentation reference of this 
 terminal, it
 would be worth to give it as it will be used in technical 
 documentations.

It's a DEC VT320, and it's second hand like all of my dumb terminals, so I've never 
actually had the original manual. Upon closer inspection, it only appears to do 
hex-byte pictures for some C1 control pictures -- see 
http://vt100.net/built-in_glyphs.html.

The VT220 did a similar thing, but more of it - no cuddly names for NEL and so on, 
plus some other chars have hex-byte pictures (probably as they were unassigned, but I 
am unsure) -- see http://vt100.net/docs/vt220-rm/table2-16b.html.

I'm pretty sure my Wyse WY60's (and probably my WY85's too) do the same thing, but 
they're so buried under junk it's probably not worth pulling them out to check.

 What you suggest is something else: it's a proposal to encode 
 technical
 characters similar to control images, or to glyphs of keys on 
 a keyboard. It
 is not a script, but a handy collection of unique glyphs.

I feel we're on the same wavelength now! :) Indeed, not a numeric system but technical 
symbols.

 In a similar technical domain, I don't know if the technical 
 glyphs that are
 (were?) used on terminals for IBM MVS systems, are all 
 encoded. I remember
 there was a sort of zig-zag arrow pointing to bottom left, as 
 well as other
 symbols denoting the current state of the terminal, and a few 
 others to
 denote editing operations in a screen mode: one had to mark a 
 edited line
 with a symbol, and the terminal took care of remember where 
 editing was
 allowed and performed, and once you had created a modified 
 line, you pressed
 a Send key to get the screen updated with the new text after editing
 operations.

Sounds very familiar :) Stuff like the stick figure (which on some terminals looked 
more like a cowboy), don't appear to be in unicode, but then again, were those 
characters ever actually a part of the IBM 3270 charsets, or were they simply internal 
only?

 This was more or less working in a way similar to the vi
 editor line-mode interface, except that it was screen-based 
 rather than
 line-based.

Looking at the original proposal by Frank da Cruz again after so long 
(http://www.funet.fi/pub/kermit/ucsterminal/hex.txt) reveals it cites many documents. 
Have a look at http://www.funet.fi/pub/kermit/ucsterminal/terminal-exhibits.pdf 
(~2.7MiB).

BTW, Frank also had other proposals which included the IBM 3270 characters I think you 
were referring to (poke around the directory at 
http://www.funet.fi/pub/kermit/ucsterminal/)..

I like the hex byte pictures proposal, and I'm seeing more reason to like it, the more 
I look into it..

Cheers!

I wasn't either - just pointing it out. I agree entirely :)

However, some symbols used as function indicators are now quite omnipotent,
and easily recognized with a well-defined meaning or function.

Some of them are encoded in Wingdings or Webdings, but some others may merit
their encoding as symbols, like:
- the note tip,
- the attachment symbol (trombonne in French, Brobriefklammer in
German, I don't know the term in English),
- the flag symbol (added by users reading lists of items, like emails in an
inbox folder or interesting products in a catalog for which a future action
is required), or the visual glasses (to mark interesting items)
- the dustbin (corbeille) used to mark items without interest,
- religious symbols commonly found in newspapers in their classified
necrologic ads.

These ideographic symbols (with a semantic meaning) are more meaningful than
various forms of dots, arrows and shapes. They will find more application
within text files than:
- conventional symbols used on geographic maps (not plain text) and that
were encoded in *dings collections,
- symbols used as road indicators (which are useful only in this context,
and dependant of local usage, and require specific ink colors, and precize
shape, and do not fit with the abstract character model)
- national/regional flags and heraldic symbols (for the same reason that
they require their ink colors and precise proportions and positioning to get
their meaning).
