Hello Gurus,

Please, please, please! I need your help badly.

The problem is with math font setup. If I use default math font, two 
problems arise:

1) Greek letters are slanted, while they supposed by our standards to be 
straight.

2) Cyrillic does not work in math, while some indexes are in Ukrainian.

I also try to setup Times New Roman (from Windows) to replace default 
math font. This would be perfect solution for me, but I've lost completely.

For my current point, I found that my TimesNR typescript behaves just 
like Gyre-Termes, so you can experiment on the latter (without need of 
Windows). This is my minimal example (see attachment also):

\usetypescript[termes]\setupbodyfont[termes, 14pt]

\starttext

Така система рівнянь має вигляд:

$это мат. текст this this math text$

\startformula\left\{ \matrix{

2 = a \cdot {2^2} + b \cdot 2 + c; \hfill \cr

1 = a \cdot {3^2} + b \cdot 3 + c; \hfill \cr

2a \cdot 2 + b = 0. \hfill \cr} \right.\stopformula

Вирішуючи цю систему рівнянь, можна отримати

всі три коефіцієнти: $c = - 2$; $a = - 1$; $b = 4$.

\stoptext


The main problem is that Latin letters in math are not slanted at all! I 
only found that some tricky conversion is done by 
original-youngryu-tx.map , but it's far beyond my understanding to fix 
something in it.

Best regards,
Vyatcheslav
