Ups, sorry ich hatte es nicht getestet ...
set MyTextFile to read (choose file)
set MyList to {"‰", "*"}
set vorkommen to 0
repeat with i from 1 to count of MyList
set MyCharacter to item i of MyList
try
set vorkommen to do shell script "grep -c " & quoted form of MyCharacter & "<<< " & quoted form of MyTextFile
end try
if vorkommen as number is greater than 0 then
display dialog "String ist nicht konsistent"
exit repeat
end if
end repeat
P.S. Das Encoding der CSV-Datei ist nicht klar?
