Re: Convert utf8 string to iso8859-1 (Latin1)

[Igor Medeiros <igorosbergster@...>]

Thank you for the quick replies.

In fact, I must to convert the string using just lua 5.1 libs due hardware issues. 

But I believe the answers are enough to perform that.

Thank you,

Igor

In Lua 5.3, that would do it:

  string.gsub(s, utf8.charpattern, function (c)
    return string.char(utf8.codepoint(c))
  end)
