A bit annoying thing in #Bsky #ATProto is that you don't post plaintext that is "enriched" remotely, but provide a Rich Text object with links, tags, etc. marked as such. It seems from the servers perspective len(rich_text)!=len(str(rich_text)) and I found no way to find out what the true length of my rich Text object will be resulting in failed posts and bad thread splitting...
