Some problems with fontspec and xelatex under windows

[maser111]

I'm using EB Garamond on Windows with MikTeX 2.9 and fontspec with xelatex. I've updated the package downloaded with MikTex (package of 5 Dec 2018). Before the update, the output have a well rendered font with oldstyle numbers and Q.long by default. After the update, the font seems the default Garamond by windows.

This is my short test.

\documentclass{book}

%\usepackage[english,italian]{babel}
\usepackage[utf8]{inputenc}

\usepackage{fontspec}
\setmainfont{EB Garamond}

\usepackage{lipsum}

\end{document}

What I'm doing wrong?

I have recreated the test file under a linux box (test - ok.pdf) and the file produced after the update on windows (test - not ok.pdf)

The long Q is located within a different stylistic set (ss) of the OpenType features, specifically in ss6. You can go through the fonts feature using FontDrop. Just drag/drop the EBGaramond-Regular.otf file there and go to the OT tab to see all the features of the fonts.

Going back to your example, changing the setmainfont options did it for me:

\setmainfont{EB Garamond}[Numbers=OldStyle, StylisticSet=6]

See section 3.1.10 and 3.1.13 on page 42 and 45 of the fontspec manual.
