Question 1

Does the character count include spaces and newlines?

Accepted Answer

Yes by default. The tool counts all characters including spaces (U+0020), tabs (U+0009), and newline characters (U+000A, U+000D). Toggle 'exclude whitespace' to count only non-whitespace characters.

Question 2

How are emoji and multi-byte characters counted?

Accepted Answer

This tool counts Unicode code points, so each emoji counts as 1 (even compound emoji like flag sequences may appear as 1). JavaScript's .length property counts UTF-16 code units, which can count some emoji as 2. This matters when setting database VARCHAR limits or API character limits.

Question 3

Why do different tools report different lengths for the same string?

Accepted Answer

Length depends on the counting unit: bytes (UTF-8, UTF-16), Unicode code points, or grapheme clusters (visible characters). A single skin-tone emoji can be 1 grapheme, 2 code points, and 8 UTF-8 bytes. This tool reports code point count, which is the most common definition.
