Character counter FAQ

Why is the X count different?

X uses weighted counting and treats many URLs as a fixed length.

Is Mastodon always limited to 500?

No. Five hundred is the default; individual instances can configure another limit.

Are emoji counted correctly?

The general counters count Unicode characters rather than JavaScript code units.
