FAQ About Unicode 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.
