The comments about only using ANSI 8-bit strings is slightly misleading in
that they do handle utf-8 as shown in the message you show, but any Lua
string functions will probably not work as expected. This is why I'm not
sure that they would be very useful.

Maybe there is a small subset of the functionality that would suffice for
you and what would that be?
