FAQ — Unicode Tool Free Online Tool

What is the difference between UTF-8 and UTF-16?

UTF-8 uses 1-4 bytes per character and is backward-compatible with ASCII. UTF-16 uses 2 or 4 bytes. UTF-8 is preferred for web and JSON.

Why does my emoji show as a box (□)?

The font being used doesn't have a glyph for that emoji. Use a font that supports the Emoji Unicode block (Noto Color Emoji, Apple Color Emoji, etc.).

What is the maximum Unicode code point?

U+10FFFF (1,114,111 code points). The Basic Multilingual Plane (BMP) covers U+0000 to U+FFFF.
