well, editors is another case as not all fonts used in editors have such
characters so your file becomes quite unportable unless the editor
implements some fallback mechanism
there's also a subscript font feature but often such features are
implemented incomplete in fonts (like frac) and quite unuseable unless
more logic in the engine is added (again, something that i will look
into when i have a reason)
Is such thing doable?
(Not making a set of mappings for presonal use, but proper package

it would be core functionality as it involved manupulating the internal
math node lists

Well, we can consider supporting linear math ..
\unexpanded\def\startmathzone
{\ifvmode
\Ustartdisplaymath
\let\stopmathzone\Ustopdisplaymath
\else
\Ustartmath
\let\stopmathzone\Ustopmath
\fi}
\defineactivecharacter 23A8 \startmathzone
\defineactivecharacter 23AC \stopmathzone
\catcode3016=\begingroupcatcode
\catcode3017=\endgroupcatcode
\utfchar{23A8}x^\utfchar{3016}1+2\utfchar{3017}\utfchar{23AC}
The question is if we do it this way using a special math catcode
regime, but that does not work when we pass it as argument unless we
mess around with some math codes - like prime does) or use a parser
(which is not that hard to do and is needed for things like sin/cos anyway)
i'll have a look at it (given that it's a frozen 'standard')

Hi Peter Khaled, I think there is a way to use ConTeXt commands inside verbatim environments, but I don't recall it. I think this is the option=commands option for setuptyping friends. AFAIK this means you need to use /TEX /ETEX around your commands or something, but I'm not completely sure. It seems this only works in MkII, it wasn't implemented in MkIV a month ago at least. Gr.

Hello,
In char-def.lua there is:
[0x2074]={
category=no,
cjkwd=a,
description=SUPERSCRIPT FOUR,
direction=en,
linebreak=ai,
specials={ super, 0x0034 },
unicodeslot=0x2074,
},
[...]
[0x2084]={
category=no,
cjkwd=a,
description=SUBSCRIPT FOUR,
direction=en,
linebreak=ai,
specials={ sub, 0x0034 },
unicodeslot=0x2084,
},
So I supposed, that the specials are for faking or simulating the unicode
character, for example ² - \superscript{2} or similar.
Perhaps, my assumption is just wrong...
I think there is a way to use ConTeXt commands inside verbatim
environments, but I don't recall it.
Yes, BTEX...ETEX, but not with the t-vim module.
Cheers, Peter

I am not sure whethere specials work at all. I am assuming that
SUPERSCIRPT ONE, TWO, and THREE work because the LM font contain them at
the right spot. These are less than hex FF. The others, for example,
SUPERSCIRPT ZERO and SUPERSCRIPT FOUR do not work because they are not
(AFAIU) mapped to any place in LM fonts. I don't even know if LM fonts
have these or not. The same is true for SUBSCRIPT.
If you use a opentype font like cambria, superscripts and subscripts work.
I guess that is because they have these symbols. If you swich to \tt with
cambria, only sup 1,2,3 work.
So, the easiest solution will be to use a (maybe) virtual font that has
these glyphs. Otherwise, using the active character trick is the easiest
option.

Most of the support is already there (except superscripts and subscripts).
MKII implemented this support using active characters (similar to what ucs
does). MKIV does this using virtual fonts.
It will give WYSIWYG-like appearance of the input file on the screen
in the editor using Unicode font and will not bring the mess deep into
ConTeXt?

(Not making a set of mappings for presonal use, but proper package

For most glyphs the support is already there. Making sure that multiple glyphs
are combined correctly is tricier. We can have an input like $ŵ¹$ and it is not
always easy to determine if it should be translated to ${\hat w}^1$ or $\hat
{w^1}$.
Microsoft implmented something like this in newer versions of Word. See the
developer's blog for more detials.
