Counts Unicode code points in your browser. Links, emoji, and platform-specific rules can be counted differently by the destination.
Why character limits matter
A post should be written for its destination, not written once and trimmed until it fits. X rewards one clear claim in a short space; LinkedIn can hold more context; Threads gives a post more room for a question and a useful detail.
Treat the limit as part of the format. Leave room for a link where the platform counts it, and remember that emoji, URLs, and server settings can affect the final count.
