LyX 1.6.5, then 1.6.6 Windows MiKTeX 2.8 Included some child documents with different encodings and got the following: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Package inputenc Error: Keyboard character used is undefined !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
As found, the solution for TeX is to insert
\inputencoding{foo}
The problem seems to be that LyX exports child documents to TeX with no
information on encoding.
Yet adding an ERT inset with that code is also a solution.
