Character limit in poll answers?

In posting previous polls, I have often come up against a character limit for the poll answers. What is that character limit, and does a spaceband count as a character for this purpose?

I have perused the sticky in IMHO about polls and this information does not seem to be in there. So please consider this also a request to add this information to the sticky.

The original limit was 100 characters.

I have changed it to 200.

Thank you.
