[NTG-context] using · in math mode

Dear ConTeXt folks, I am using the Neo keyboard layout [1], which enables me to directly enter several UTF-8 characters. The dot »·« is one of those characters [2] and I like to use it in math mode instead of `\cdot`. But in math mode it is some kind of bold lower dot (see attachment) and not ·. In works fine “text mode”. \starttext $a · b = a \cdot \text{ (\\cdot) } b = ab$ in text · \stoptext Is the wrong UTF-8 character used or can ConTeXt be adapted to use »·« as would like to? Thanks, Paul [1] http://www.neo-layout.org/ [2] http://wiki.neo-layout.org/browser/A-REFERENZ-A/neo20.txt#L225
