}Check a caption
Counts a post's text the way Instagram, Facebook, YouTube, TikTok, LinkedIn and X count it, against each platform's limits: characters, X's weighted 280 (emoji 2, links 23), TikTok's UTF-16 2,200, YouTube's 100-character title and 5,000-byte description, Instagram's 5 hashtags and 20 mentions. Returns each platform's counts, limits and whether it fits.
