CSVDataError: Illegal State - Only in IE about jquery-csv HOT 3 OPEN

It appears that this was an issue caused by french characters (é, à, etc.).  
FireFox and Chrome handled these characters without any problems but IE 
continued to fail, regardless of any charset used with the ajax call.  
Stripping the file of any french characters appears to resolve the issue.  It 
would be much appreciated if further support could be implemented to prevent 
this from being an issue as additional steps need to be taken now when 
generating the CSV file to ensure there are no French characters.

Are you reading the data from a file or an AJAX request? If so, are you setting 
the encoding to utf8.

AFAIK, the parser should work with utf8. If it's not working with utf8 then 
perhaps a change can be made to fix the issue. 

Excluding french-specific chars shouldn't be necessary

It appears that -- in older versions of IE -- if you don't force Internet 
Explorer to use the UTF8 encoding, it will default to whatever language the 
browser client uses. For example, if you're using a french version of IE the 
browser will default to using a french-specific encoding.

You may try to set the encoding explicitly in the HTML header with:
     <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
