definitely contain all bytes, including control characters like \026. However,
you should not put such binary > data directly inside *literal* strings that
are fed to the Lua parser. You need to use escape sequences to encode all
nonprintable characters. (The current > implementation does tolerate most of those, but notably
not newlines, and you should not count on this behavior.) 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 Paul |
