New updates in TeX Live may have some issues. Now I have this new error with the Charis SIL font compiling with LuaLaTeX. If I change the font (say Gentium Plus) the error is gone.
LaTeX3 Error: Key 'fontspec-renderer/Renderer' accepts only a fixed
set of(LaTeX3) choices. ]
EDIT: I use Charis SIL font with
\setmainfont{Charis SIL}[ Renderer = ICU ]
to get smallcaps, just found that Renderer = ICU is the problem, without it, the problem is gone.
My concern is about what happened? I use this config for years and today failed.
EDIT 2: This is a MWE
\documentclass{article}
\usepackage{fontspec}
\setmainfont{Charis SIL}[
Renderer = ICU
]
\usepackage{lipsum}
\begin{document}
\lipsum[1]
\end{document}
EDIT 3:
Forget about Renderer = ICU, my mistake. My point is there is some problem with fontspec and Charis SIL . I have this MWE that compiles fine in MacTeX but give errors in Ubuntu 18.04, TeX Live 2018, both updated. But if I change the font (say Gentium Plus) errors are gone.
\documentclass{article}
\usepackage{fontspec}
\setmainfont{Charis SIL}[%{Gentium Plus}[%{Charis SIL}[
Ligatures = TeX,
]

\usepackage[activate={true,nocompatibility},final,tracking=alltext,letterspace=-10]{microtype}
\usepackage{lipsum}
\begin{document}
\lipsum[1]
\textsc{Hello World!}
\end{document}

And the main point is that I had use several files with similar templates, involving Charis SIL for a couple of years, but yesterday (feb 26,2019) all of them fail compile. Same files work fine if I change the font to Gentium Plus.
