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.

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

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:

context symbols.tex

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.

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.

To avoid this you can define % your own symbol or just put the character in your document % without the \symbol command. \definesymbol[blackdiamond][◆] \starttext direct input: ◆ \type{\symbol[blacktriangle]}: \symbol[blackdiamond] \stoptext Wolfgang

Otared, Wolfgang:

Thank you for your suggestions.

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

\starttabulate[|l|c|] \NC \bf Name \NC \bf Symbol \NC\NR \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 \NC square \NC \symbol [square] \NC\NR \NC diamond \NC \symbol [diamond] \NC\NR \TB \NC blacktriangle \NC \symbol [blacktriangle] \NC\NR \NC blacksquare \NC \symbol [blacksquare] \NC\NR \NC blackdiamond \NC \symbol [blackdiamond] \NC\NR \TB \NC 1 \NC \symbol [1] \NC\NR \NC 2 \NC \symbol [2] \NC\NR \NC 3 \NC \symbol [3] \NC\NR \NC 4 \NC \symbol [4] \NC\NR \NC 5 \NC \symbol [5] \NC\NR \NC 6 \NC \symbol [6] \NC\NR \NC 7 \NC \symbol [7] \NC\NR \NC 8 \NC \symbol [8] \NC\NR \stoptabulate

\stoptext %%%% end example

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

(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.
