url ical error if description length>1000 then add in google calendar

hi
I try to add event to google calendar via url.
if my description is more then 1000 symbols I have error “Google Invalid request.”

if I change file em-event.php line 1809
if( strlen($gcal_url_description) + $gcal_url_length > 1350 ){
$gcal_url_description = substr($gcal_url_description, 0, 1380 – $gcal_url_length – 3 ).’…’;
to
if( strlen($gcal_url_description) + $gcal_url_length > 1000 ){
$gcal_url_description = substr($gcal_url_description, 0, 950 – $gcal_url_length – 3 ).’…’;

and it is ok!
ical google limit is 1000.

Can you add this in next update for file em-event.php?
Or may be I can change ical limit in other way?
thank you.
