Convert utf8 string to iso8859-1 (Latin1)

[Igor Medeiros <igorosbergster@...>]

Dear contributors,

Is there a way to covert a string whose characters are encoded in utf8, to a string with characters encoded in iso-8859-1, just using lua standard libs? I cannot use libs with C codes.

If there is, could you tell me how to do that or even point some site with this information?

Thank you

Igor
