Hi Jelmer,
The error occurs spasmodically when somebody uses the email functions. I have added an error-logging post message to save the $str and will monitor any future occurrences.
I did not notice that iconv(...) was a PHP function and thought it was a CI problem. I also had a quick look at the PHP documentation which was quite involved and will try again tomorrow, hopefully with a clear head and try to resolve the issue.
Many thanks for clarifying the error.
