Why Social Media Character Limits Matter
Every social platform uses strict length limits to keep feeds scannable. Staying within character constraints ensures your headlines don't get truncated by "...more" buttons and prevents SMS messages from splitting into expensive multi-part billings.

Frequently Asked Questions
❓ Why do emojis count as two characters on Twitter?
Twitter utilizes UTF-16 code units for measuring character length. Most emojis (such as ✨, 🚀, or 🔤) reside in Unicode Supplementary Planes requiring surrogate pairs (4 bytes), counting as 2 characters.
❓ What causes an SMS message to split into multiple segments?
Standard English SMS messages use 7-bit GSM-7 encoding (160 characters per segment). If any non-GSM character (such as an emoji, smart quote, or accented letter) is present, the message switches to 16-bit UCS-2 encoding with only 70 characters per segment.
