Bluesky Character Counter

Bluesky counts posts in grapheme clusters rather than raw code units. That means a flag emoji, a family emoji or an accented character built from two code points counts as a single character.

This counter uses the Unicode grapheme segmentation rules Bluesky uses, so the number here matches what the app accepts.
