Thanks for all your suggestions. In my case the usage model is a bit more complicated. I use Lua linked to some C++ code that acts as a host and calls Lua functions to provide scripting functionality used mainly for testing. So ultimate Lua users and writers in my case are testers and it’s their scripts where *literal* strings with \026 characters come from. My current plan is to explain them that they can’t use \026 characters directly and have to escape them but ideally I’d like to avoid this. Any suggestions how to make their (and mine) life a bit easier are very welcome J
