Per https://github.com/mastodon/mastodon/blob/963a54664804e60ea8e30795090a0f20de7a48dc/FEDERATION.md#size-limits each activity object has a maximum size of 1 MB; that is including various metadata, but not attachments (they're stored as URLs). So it should give like a few tens of thousands characters to work with, in theory. With that said, if you've seen WordPress blog posts inside Mastodon it just doesn't look as good in a frontend designed for microblogging... (Also note that the only way for instances to configure character limit is by patching the code.)
