[NTG-context] Units module and unbowed letters ..

Hello ConTeXist. When I work with Units module, I gain at the output of the greek "mi" letter an italic font. It seems strange. It is so in terms of typography correctly or not? Can also be used for typing (with units module) unbowed letters? Thanx Jaroslav Hajtmar Here is my example: \usemodule[units] \usetypescript[times][texnansi] \setupbodyfont[times,12pt] \starttext 5\,\Micro\Meter 5\,\uMeter 5\,μm \stoptext
