Placing a scaled symbol within the flow of text

Placing a scaled symbol within the flow of text

[Pearson, Mark (Capita Symonds)]

Hi all,

I am attempting to insert a symbol at a reduced size within the
text flow but I'm not sure how to achieve this.

I've included my test script below. 

\starttext

\definefontsynonym[Dingbats][uzdr]
\definesymbol[filledSq][\getglyph{Dingbats}{\char110}]

\def\FilledSq{\symbol[filledSq]}
\def\FilledSquare{\scale[height=0.5ex]{\symbol[filledSq]}}

\switchtobodyfont[20pt]

\startlines
\FilledSq Here is a line
This is one line
and this should be another
\FilledSq Hello again 
\FilledSquare and again!!
and here are some more lines
this is the last one
\stoplines

\stoptext

When a \FilledSq is inserted, the text which follows appears 
on the same line but when a \FilledSquare is inserted the text 
which follows appears on the line below. I'm probably using 
\scale in an inappropriate way and I'm sure don't know my
\vbox's from my \hbox's!

Any examples of how to reduce the size of a glyph whilst
still being able to insert it as a normal character in the 
text flow would be greatly appreciated.

Thanks,

Mark Pearson

In TeX terms, \scale creates a \hbox. If TeX is in vertical
mode (as it is when \startlines is in effect, because every line
is a paragraph by itself in the mode), then a simple \hbox is
not a good enough hint to make it switch to horizontal (paragraph)
mode. So need another command to switch TeX to paragraph building
mode, and it is:

   \def\FilledSquare%
     {\dontleavehmode\scale[height=0.5ex]{\symbol[filledSq]}}

Cheers, Taco
