Hello guys, am working with some basic maths here and the latest version of
ConTexT. However, i think something has changed in ConTexT, because the
following MWE, from Aditya, was working fine before:

\definefontfamily[mainface][rm][Minion Pro]
\definefallbackfamily[mainface][math][Minion
Pro][math:lowercaseitalic][force=yes]
\definefallbackfamily[mainface][math][Minion
Pro][math:digitsnormal][force=yes]
\definefontfamily[mainface][math][TeX Gyre Pagella Math]
\setupbodyfont[mainface]

\starttext
\startformula
c^2 = a^2 + b^2
\stopformula
\stoptext

Now, the italic font of Minion Pro is replaced for regular.
Well, i have two questions:

1) How can i set the Minion Pro italic font for math?
2) Is there any way to set the italic font for numbers too in math?

Thank you guys.

It’s a bug but I fixed it.

Wait for the next ConTeXt version.

Thanks Wolfgang,

For now, am using this work around to get italic in maths:

\definefallbackfamily[mainface][math][Minion
Pro][tf=style:italic,preset=math:lowercaseitalic]

I have another couple of questions:

1) I am using a font that have the feature onum enabled by default, so
how can i unset this feature for math (lnum,tnum)?
2)  Is there any way to use only some symbols like +, - from Minion
Pro in math mode?

Hello list,
I have another question for you, it is about diacritic's replacement
in math mode.

\definefontfamily[mainface][serif][Minion Pro]
\definefallbackfamily[mainface][math][Minion
Pro][tf=style:italic,preset=math:lowercaseitalic]
\definefallbackfamily[mainface][math][Minion
Pro][tf=style:italic,preset=math:uppercaseitalic]
\definefontfamily[mainface][math][Latin Modern Math]
\setupbodyfont[mainface]

\starttext
{\it Piña}\par
\m{Pi\tilde{n}a}\par
{\it Canción}\par
\m{Canci\acute{o}n}
\stoptext

As you can see, the accents are replaced with Latin Modern Math font.
So, how can i use accents from Minion Pro?

You have to create a font feature where you change the number style and 
apply it with the features key.

\definefontfeature[mathdigits][default][mode=base,onum=no,lnum=yes]

\definefallbackfamily [...] [mm] [...] 
[preset=math:digitsnormal,features=mathdigits]

> 2) Is there any way to use only some symbols like +, - from Minion

You can select certain characters with the range key but you have to 
know the unicode numbers.

\definefontfamily     [mainface] [rm] [Minion Pro]
\definefallbackfamily [mainface] [mm] [Minion Pro] [range={0x002b,0x2212}]
\definefontfamily     [mainface] [mm] [TeX Gyre Pagella Math]

\setupbodyfont[mainface]

\starttext
\m{12 + -3}
\stoptext

Use the \mathtext (ot \mathtextit, \mathtextbf etc.) command.

\definefontfamily [mainface] [rm] [Minion Pro]
\definefontfamily [mainface] [mm] [Latin Modern Math]

\setupbodyfont[mainface]

\starttext

{\it Piña}

\m{\mathtextit{Piña}}

{\it Canción}

\m{\mathtextit{Canción}}

\stoptext

Many thanks Wolfgang!
BTW, how can i know what symbols are in range={0x002b,0x2212}?
