Beginning with LuaMetaTeX (LMTX) versions after January 2021, there is a new mechanism for typing some composed characters, that is characters with some sort of diacritic signs, such as {{code|\'e}} in order to obtain « é », or {{code|\c c}} to obtain « ç ». Actually most of these characters have a UNICODE definition and can be typed directly from some keyboard configurations. But in order to have backward compatibility, and at the same time allow the user to type them through a command, the following commands are made available.
First of all the command {{cmd|chr}} creates the specified composed character: for instance {{code|\chr{a acute}}} results in « á ». The same can be obtained with {{code|{\withacute a}}}
Here are a few of them, the complete list can be seen by typesetting the file {{code|s-characters-combinations.mkxl}}, or by copying the code below and typesetting it with LMTX.
