[valentjn]

It works when using \v{Z}\'{a}k, or when using Unicode (LuaL^AT_EX).

I'll have to see whether this will be fixed. Formally, { ... } is opening a new group, which could contain anything, really (not just a single letter), and it's pretty plain-T_EX-ish.

[github-actions]

This issue is now fixed on develop. The fix will be included in the next release of LT_EX.

If you don't want to wait, you can try out the nightly pre-release tomorrow. Nightly pre-releases are published every morning at around 4am UTC.
