Format of Notes in Timesheet entry

Format of Notes in Timesheet entry

Hello 

I am trying to import timesheets from an existing program.  

I've been using:  http://www.zoho.com/projects/developers/timesheet-api.html#2

I have a working example with a simple lognotes field. Something like:  "Here is a note"  works.

What doesn't work is something more complicated like:

-Here is a note
~some more stuff
[blah] blah blah blah
~notes notes notes
-notes notes notes

The above returns a 500 server error after request.

The above will work in the timesheet input page:   https://projects.zoho.com/portal/{MYPORTAL}#mytimesheet

I am url encoding my fields of course.

Please provide some details about what inputs for the lognotes field will work.

Thank you.


EDIT:  I suspect that the problem could be the character count of my lognotes field input.  I took a large example and removed all white-space non alpha characters and I lower cased the whole string.  Still the post returned a 500 error.  Is there a maximum character count on the  lognotes input? If so what is that maximum?
