[NTG-context] vanishing leftarrow

20 Nov 2002

      I did encounter something strange with leftarrow in metapost math:

In normal text:
All three arrows appear with $l\leftarrow r\rightarrow 
lr\leftrightarrow$.

In metapost:
The leftarrow does not appear, the others do in:
	\placefigure{}{\startMPgraphic
		u = 180mm; v = 40mm;
		label.bot(textext("$l\leftarrow r\rightarrow 
lr\leftrightarrow$"),(u/2,v));
	\stopMPgraphic\loadcurrentMPgraphic{}\placeMPgraphic}

How is that possible and how can it be repaired?
