UTF-8 Encoder / Decoder

About UTF-8 Encoder/Decoder

UTF-8 encodes Unicode characters as variable-length byte sequences. When apps show “é” instead of “é”, you are usually looking at UTF-8 bytes misread as Latin-1—this tool helps inspect the real bytes.

Unicode vs HTML formatting

Hex shows raw bytes. UTF-8 tool focuses on character ↔ byte relationships for international text debugging.

Platform compatibility

Use when APIs declare charset=utf-8 but logs show garbled accents. Pair with URL decoder when errors involve % sequences.

How to Use UTF-8 Encoder/Decoder

1. Paste text to see UTF-8 code units/bytes.

2. Paste byte notation to recover characters when possible.

3. Compare output with your database or API charset settings.

Examples

• é → UTF-8 bytes C3 A9
• Hello 世界 — mixed ASCII and CJK
• 😀 — mojibake hint (investigate wrong decode)

When to Use UTF-8 Encoder/Decoder

i18n QA Verify emoji and accents survive API round trips.

Database migrations Confirm column charset matches app encoding.

Log forensics Interpret byte columns in support tickets.

Why Use This UTF-8 Encoder/Decoder?

Visualizing bytes beats guessing which charset went wrong.
