Hi to all.

I'm trying to build a loader for csv file. As you can see from the code I load my csv file in an attachment. After I take the body of the attachment and insert it into a string using the toString (). I noticed that when in the csv file there is the € symbol I get an exception of type 'BLOB is not a valid UTF-8 string'. Do you have any suggestion?

My Controller

public with sharing class DocumentwithEuroController {

	public Attachment document {
			get {
				if (document == null)
					document = new Attachment();
				return document;
			}
			set;
		}
		
		
	public PageReference checkFile() {
		
		
		String fileBody = '';
		
		try{
			fileBody = document.body.toString();
			system.debug(fileBody);
		}catch(exception e){
			if(e.getmessage() == 'BLOB is not a valid UTF-8 string'){
			
				ApexPages.addMessage(new ApexPages.message(ApexPages.severity.WARNING, 'In the csv file there are stressed symbols. The upload is blocked'));	
			
			}
		}
		
		
		
		return null;
	}	

	
	

}

My page.

<apex:page controller="DocumentwithEuroController" >
 
<apex:form >

<apex:pageMessages id="pms1" />

<label for="ifl"
						style="text-align: left; font-weight: bold; padding-right: 0.69em;">Selezionare
					il file tracciato(.csv):</label>
					<apex:inputFile id="ifl" value="{!document.body}"
						filename="{!document.name}" styleclass="btn" />
						<apex:commandButton value="Load csv" action="{!checkFile}"
				status="loadCsv" />

</apex:form>

</apex:page>

For me is very important, i must resolve this proble by tomorrow 

Tanks to all,
