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?
