inspect does not render non printable values correctly about inspect.lua HOT 7 CLOSED

I could open a pull request if this is required. inspect.lua could check to see if each character is outside the printable range (20 - 126 inclusive) and then replace it with an escape sequence...

Actually, hold on one minute.

Test case...

So the problem is only with \127?

Yes, as far as I can tell

I didn't notice this issue was open, apologies for that.

Some people consider the DEL character (char code 127) as "printable". I must have used some resource that did that, but TBH I didn't even think about it. I believe that it should be displayed. I will mark this as a bug.

Control characters shouldn't be output verbatim, even if lua strings are completely binary safe, since inspect.lua's purpose is to output something to be read by a person, at least as far as I know.

Thanks for reporting this, I have released a fix that should properly escape DEL and released a new version of the luarock with it.
