Hi, Susanne.

I think you're confusing ConTeXt symbol sets with LaTeX ones. Except for symb-imp-emj, which is for emoji support, files with symb-imp prefixes list symbol sets supported by ConTeXt (see /tex/texmf-context/tex/context/base/mkiv):

symb-imp-cc

symb-imp-cow

symb-imp-eur

symb-imp-fontawesome

symb-imp-jmn

symb-imp-mis

symb-imp-mvs

symb-imp-nav

symb-uni.mkii is not available for ConTeXt MkIV, but you could make it work with a proper font set (e.g. Quivira) or better, ask Hans for it.

Wrt ifsym itself, it is a LaTeX specific package and it won't work out of the box, so you could 1) use a Unicode alternative instead or 2) adjust Metafont files so they could be compiled via Metapost. If you go for 2), the following would work as a poor's man solution for any symbol you need.

\starttext

\startuseMPgraphic{Flag}

%From ifsym.gen

draw (3pt,0pt)--(3pt,10pt);

fill (3pt,10pt)--(0pt,8pt)--(3pt,6pt)--cycle;

\stopuseMPgraphic

This is a poor's man \type{ifsym's \Flag}: \useMPgraphic{Flag}.

\stoptext

There's a more advanced way to register glyphs explained in Luametafun (http://www.pragma-ade.com/general/manuals/luametafun.pdf), in case you're interested.

Regards,

Jairo :)

Dear Reader, 

https://wiki.contextgarden.net/Symbols shows predefined symbol sets. The uni and wasysym are unknown. 

Hereby my example: 

\usesymbols[mvs]

\usesymbols[uni]

\usesymbols[wasysym]

%% \usesymbols[ifsym]

\starttext

\par Show entire set martinvogel 1

\showsymbolset[martinvogel 1]

\par Show YinYang symbol from martinvogel 2. \crlf

\symbol[martinvogel 2][YinYang]

%% \symbol[Alpine Symbol][Flag]

\stoptext

Console output

fonts > symbols > library 'mvs' loaded

fonts > symbols > library 'uni' is unknown

fonts > symbols > library 'wasysym' is unknown

The ultimate goal is to show a flag from the alpine symbol set from ifsym. However, I will settle with a flag from uni if it means I don't have to install files.

Kind regards,

Susanne
