Wrong upright Greek instead of Italic

Wrong upright Greek instead of Italic

[Khaled Hosny]

This gives me upright Greek, but I was expecting italic:

\setupbodyfont[xits]
\starttext
$\mathit{ΑΒΓΔΕΖΗΘΙΚΛΜΝΞΟΠΡΣΤΥΦΧΨΩ}$

$\mathbi{ΑΒΓΔΕΖΗΘΙΚΛΜΝΞΟΠΡΣΤΥΦΧΨΩ}$
\stoptext

What happens if you key in the actual unicode values (sorry no ConTeXt 
right now)?

I get the correct style as typed.

Then this is a bug in the mappings (and I assume that Cambria also does 
not work). I will test later.

Or even LM, all give me upright instead of italic.

Currently, \mathit does not set the attributes for greek. The italic
attributes for greek are set by \mathgreekitalic and \mathgreekupright (but
see below).
\mathit can also set \mathgreekitalic. But I am not sure if it should.

However, there is a bug in \mathgreekupright and \mathgreekialic: they set
the wrong numerical values for attributes. The correct definitions are:

\unexpanded\def\mathgreekupright{\attribute\mathgreekattribute22 }
\unexpanded\def\mathgreekitalic {\attribute\mathgreekattribute33 }

and then you can use  \mathgreekitalic  and \mathgreekitalic\bf instead of
\mathit and \mathbi.

@Hans, can you correct these definitions in math-ini.mkiv.

BTW, I did not know that you could use \setupbodyfont without the
\usetypescript line.

I learnt it by accident, looks like some mkiv goody or something.

I added that a while ago for mkiv, where it's doable as we don't have to 
specify font encodings (\settrue\autotypescripts is default). Actually, 
it will also try to load type-<askedname> when no match is found, so you 
can make type-mycombi.tex with a mycombi typescript and then 
\setupbodyfont[mycombi].

Hi Khaled,

Do you use 
\setupmathematics[ucgreek=italic]
at the top of your file?
Here I do get italic Greek letters if I add the above command to your example.

Best regards: OK

But then \mathrm will be italic too, since I'm explicitely selecting the
style, the setup should make no difference, which is indeed the case with
Latin.
