<br>
I don’t have an up-to-date installation to test with on this machine and I can see there may be some interactions between newer LaTeX2e code and fontspec that I need to take into account. I can also see I need to add an interface to change the default encoding for different font families. With that being said, does the example document below appear to work for you?<br>
<br>
It’s a bit fragile in terms of loading order and needing that initial \rmfamily. Once we have an example that I can work towards I can try to improve the fontspec behaviour...<br>
<br>
Many thanks,<br>
Will<br>
