Thanks very much for your response
I've downloaded the last version of hotpot, I've opened and recorded my hotpot files with this version.
Now, all problems with accents disappeared.
I'm sorry to have disturbed you.
I send you (see attached files) a quiz not modified that doesn't work with é an è (replaced by ?)
I 'll test the new hotpot module
Thanks again for your super work and "longue vie" to hotpot module
