Re^2: XML::Simple parser error : Input is not proper UTF-8, indicate encoding

I solved the problem by replacing non-printable characters to nil, before writing to XML file. My regular expression is as follows.

  # following is a code to remove non-printable characters in string i
+ncluding newline
  s/[^[:print:]]+//g;
  # this pattern won't remove newline char
  s/([\x00-\x09]+)|([\x0B-\x1F]+)//g;
