Many thanks for your reply, Hans.

It seems that Literata has what they call an upright italic
(https://raw.githubusercontent.com/googlefonts/literata/main/Documentation/DS_Literata3.pdf#search=upright).

But I’m afraid I cannot use weight (when invoked as 'wght'). Optical
sizes don’t seem to work.

The following code shows the issue I’m experiencing:

  \definefontfeature[myaxis][axis={wght=100, opsz=1.0}]
  \definefontfamily[mainface][rm][Literata]
    [features={default, myaxis}, designsize=auto]
  \setupbodyfont[mainface]
  \starttext
  \scale[width=\textwidth]
    {\switchtobodyfont[7pt]\tf Regular, \it Italic}
  \scale[width=\textwidth]
    {\switchtobodyfont[12pt]\tf Regular, \it Italic}
  \scale[width=\textwidth]
    {\switchtobodyfont[36pt]\tf Regular, \it Italic}
  \scale[width=\textwidth]
    {\switchtobodyfont[72pt]\tf Regular, \it Italic}
  \stoptext

What am I missing here?

Many thanks for your help,

Pablo
