Question 1

Why do character counts differ between platforms?

Accepted Answer

Different platforms count differently: Twitter counts emojis as 2 characters, some count spaces, newlines vary. Unicode characters may count as 1 character but multiple bytes/code points.

Question 2

What is the difference between characters, words, and bytes?

Accepted Answer

Characters: individual symbols. Words: space-separated groups. Bytes: storage size (1 ASCII char = 1 byte, but Unicode chars can be 1-4 bytes). Emoji often = 4+ bytes but 1 visual character.

Question 3

What character encoding should I use?

Accepted Answer

UTF-8 is the modern standard - it handles all characters and is backward-compatible with ASCII. Use it unless you have specific legacy requirements.

Question 4

Will encoding/decoding change my data?

Accepted Answer

Proper encoding is reversible. However, using wrong encoding can corrupt special characters. Always use the same encoding for encode and decode.
