how to insert symbols into document?

how to insert symbols into document?

[Csikos Bela]

Hello context users:

I would like to insert symbols into my document, especially black-diamond and losenge
symbols. I read symbols page at contextgarden but still don't know how to do it.

I also tried \showsymbolset[was] etc but the symbols but I did not find these (and many
other symbols either) in the output pages.

I found that symb-imp-mis.mkiv file defines this symbol (line 49) but I don't know how to
make it show. Do I have to load specific symbol fonts? If yes how can I find out which font has the given symbols? 

What I tried so far included:

% begin code
\usesymbols[imp-mis]
\starttext

◆

\blackdiamond

\symbol [blackdiamond]
% end code

None of these show anything.

Thanks in advance,

bcsikos

Hi,

You can use the mathmode to access those characters, as in the following example:

\starttext
This is \type{$\blacklozenge$} $\blacklozenge$

This is \type{$\lozenge$} $\lozenge$
\stoptext

If you want to know the name of some specific characters you can use the following code, typeset in mkii.
(Unfortunately in mkiv the command \showmathcharacters is made unavailable… There is another command which gives a huge amount of informations on all such characters, but not a simple table like the one you get in mkii).

%%%% begin show-math-mkii.tex
% To see all the math characters available in a font
% typeset this in mkii
\starttext
\showmathcharacters
\stoptext
%%%% begin show-math-mkii.tex


Best regards: OK

Hi,

The above example works.
But if I try it with \blackdiamond, I get error and context stops:

This is the tex file:

% begin code
\starttext
This is \type{$\blackdiamond$} $\blackdiamond$

This is \type{$\diamond$} $\diamond$
\stoptext
% end code

And the compilation:

How can fix this?

Re: how to insert symbols into document?

[Otared Kavian]

Hi,

There is no \blackdiamond defined beforehand, but there is \diamondsuit (as well as \heartsuit, \spadesuit, \clubsuit):

If you want a filled black diamond, you may use \blacklozenge, or find its corresponding UTF code and then insert it with a special command:

%%%% begin diamond.tex
\define\blackdiamond{\utfchar{"2666}}
\starttext
This is \type{$\diamondsuit$} $\diamondsuit$

This is \type{$\diamond$} $\diamond$

This is \type{$\blackdiamond$} $\blackdiamond$
\stoptext
%%%% end diamond.tex

Best regards: OK

The symbols in the file symb-imp-mis.mkiv are loaded by default because context uses
them for the itemise environment but a few of them have to be enabled before you can
use them and even then you need a font which contains them, e.g. DejaVu.

%%%% begin example
\setupbodyfont[dejavu]

\setupsymbolset[text]

\starttext

\TB
\NC bullet        \NC \symbol [bullet]        \NC\NR
\NC dash          \NC \symbol [dash]          \NC\NR
\NC star          \NC \symbol [star]          \NC\NR
\NC triangle      \NC \symbol [triangle]      \NC\NR
\NC circle        \NC \symbol [circle]        \NC\NR

When you need characters like the mentioned losenge you should better look for a font
which contains it and create a new typeface for it or set a fallback font which add the
characters to the main font of your document.

OK, I see that neither the default font nor Tex Gyre Pagella has black diamod symbol, therefore it can't be shown.

Before answering I wanted to find out how to make this fallback: Using a given font
and fall back to only one (or a few) specific characters in another font. For example
using Tex Gyre Pagella and fall back to Dejavu's black diamond, but not to any other
characters.

To learn how to do this, in the last few days I read most of (if not all) the related pages on
the wiki site, and browsed the indicated pdf documents too. Unfortunately I find the wiki
pages confusing, and I couldn't find out how to solve the problem yet, but I did not want
to wait longer with the answer. I will study further the docs.

Thanks once more for your help,

bcsikos

search for 'fallbacks' in the test suite

(you can have fallback ranges but also individual characters)

Fallbacks don’t work when you use \iffontchar to check if the character is in the font
even though it is available in the fallback font.

\definefallbackfamily [testfont] [rm] [DejaVu Serif] [range=0x25C6]
\definefontfamily     [testfont] [rm] [TeX Gyre Pagella]

\setupbodyfont[dejavu]

\starttext

◆ : \checkedtextchar{"25C6}{{\tttf ??}}

\switchtobodyfont[testfont]

◆ : \checkedtextchar{"25C6}{{\tttf ??}}

\stoptext
