You need a font with the character or use fallbacks.

@Hans: Shouldn't the output contain a notdef char.

Please explain "use fallbacks".

Thanks.

Unicode values [1], in the example above all characters with a code  
between
0x0060 (grave accent) till 0x0070 (latin small letter p) are taken from
the current font for the slanted style.

\def\crosssign{\utfchar{"271D}}

You need only a font the symbol, if you have one there are different
ways to use it.


The simple solution:

\definefont[unicode][name:unicodesymbols*default]

\def\crosssign{\utfchar{"271D}}

\starttext

text {\unicode\crosssign} text

\stoptext

You can also include the font in the defintion of \crosssign.


The advanced solution:

\def\crosssign{\utfchar{"271D}}

\definefontsynonym[UnicodeSymbols][name:unicodesymbols*default]

\definefontfallback[symbols][UnicodeSymbols][dingbats]

\starttypescript [serif] [mine]
   \definefontsynonym [Serif] [TeXGyrePagella-Regular]  
[fallbacks=symbols]
\stoptypescript

\definetypeface [mine] [rm] [serif] [mine] [default]

\setupbodyfont[mine]

\starttext

text \crosssign\ text

\stoptext

You need a few more lines for the setup because you need
a new typescript.

  Can you send a precise example, specifying in particular the font you use?

Thank you for the very quick answer. I read Mr. Lindsay's instruction. 
It worked, and quite easily. I also tried to just use the character in 
mkiv. That didn't work. However, in mkii, I tried the following:

\usesymbols[uzd]
\definecharacter crosssign    {\uchar{39}{29}}
\starttext

Here is the \crosssign\ in a sentence.

\stoptext

That worked too, and seems easier.

I would like to figure it out it mkiv as well. I type the character in 
VIM, but it showed up as a space in the PDF.

  You probably mean U+217D, not U+271D.

  This is one of the famous Zapf dingbats, available in dedicated fonts;
you don't really need Unicode fonts in order to typeset it.  Try the
instructions by Adam Lindsay
(http://web.archive.org/web/20061130021250/homepage.mac.com/atl/tex/ZapfDingbats.pdf)

  An alternative with Mark IV: just find a font that contains that
character.  You can look for it with BabelPad on Windows /
UnicodeChecker on Mac OS / gucharmap on Linux.  Then, just use the font
with the \definefont command.

Unicode Characters

[Erich R Fickel]

I am trying to insert unicode charater 217D (a cross) into a line of 
text. I cannot figure out how to do it, or if it can be done. I use mkii 
but could be convinced to move to mkiv if necessary.
