Dear Sirs,

I have a problem with displaying some special characters from the AMS
Symbol-fontset, e.g. \blacksquare, \blacktriangle, ...

The symbols are displayed under MkII but not under MkIV.
(MkII and MkIV-version: 2010.05.24)

The symbols  are defined in "math-ent.lua", but how can I call this file
to show the missing symbols?

Is it possible to make a link to the now-non-existing Module "amsl" so I
can use old ConTeXt-documents without changes?

Thanks for your help
Bernd Kosubek
