Dear list,

I think I stumbled into a bug in the latest beta.

When using Minion Pro, ConTeXt changes a colon to an apostrophe. A 
minimal example:


\definefontfamily [mainface] [rm] [Minion Pro]
\setupbodyfont[mainface, 12pt]

\starttext

a: b

\stoptext


I think this was introduced so long ago. I do not track all the updates, 
but I update fairly regularly, and one of my older installs did not have 
the bug in question. Also TeXLive 2015 gets it right.
