I have been trying to create a post in the Canada community. Scuttlebutt is that the post limit was set to 10,000 characters, but has since been set to 50,000 characters. My post has 9961 UTF-8 characters (9969 characters overall, 8396 characters excluding spaces) and when I hit submit the submission never completes.
hmmm. and it looks like the commit to add the 10k limit in the backend was only added in v0.18. will investigate this some more.
