character limit in PICO-8

So, I'm relatively new to PICO-8, and while looking for information on the token limit, I found a post mentioning that there's also a character limit.
Perhaps I'm completely blind, but unlike the token limit, which is constantly displayed, I can't find where this character limit is indicated.
Since I rely heavily on comments to navigate my code, this might cause me problems at some point. Could someone point me in the right direction ?
