Här kommer en liten kodsnutt man kan använda i Inobiz för att filtrera bort oönskade tecken i ett edifactmeddelande:

/*
  input = string to process,
  charset = charset to use (unoa, unob, unoc)
  mode = alphanumeric or numeric (an, n)
  length = length of resulting string (including decimals)
  decimals = number of decimals (only used when mode == "n")
*/
string EdiString (string input, string charset, string mode, integer length, integer decimals)
{
  string regex, schar, editmask;
  
  if (mode == "n")
  {
    if (decimals > 0)
      editmask = "-" & fill ("Z", length - (decimals + 2)) & "9P" & fill("9", decimals);
	else
      editmask = "-" & fill ("Z", length - 1) & "9";
			
    input = removechars(edit(input, editmask), "+");
  }
  else
  {	
    if (tolower(charset) == "unoa")
    { 
      regex = "[^0-9A-Z.,_()\\/=\\\\\\+:?\"!'%&*;<> ]";
      input = translate(input, "åäöÅÄÖ", "aaoAAO");

    }
    else if (tolower(charset) == "unob") 
    {

      input = translate(input, "åäöÅÄÖ", "aaoAAO");
    }
    else /* defaulfs to unoc */
      regex = "[^0-9a-z.,_()\\/=\\\\\\+:?\"!'%&*;<> A-ZåäöÅÄÖ]";
	  
    for (integer i = 1; i <  strlen(input) ; ++i)
    {
      schar = strpos (input, i);
			
      if (regexp(schar, regex) == 1)

      }
