Frequently Asked Questions

What's the difference between UTF-8, UTF-16, and ASCII?

UTF-8 is variable-length (1-4 bytes) and supports all Unicode characters. UTF-16 uses 2 bytes per character and is common in Windows/Java. ASCII uses 1 byte and only supports basic English characters (0-127).

How do I know which encoding to use?

Use UTF-8 for most modern applications and international text. Choose UTF-16 for Windows/Java environments or when working with systems that specifically use it. ASCII is for simple English text or legacy systems.

What happens with invalid hex data?

DevHelper provides clear error messages for invalid hex input, such as odd-length strings, non-hex characters, or malformed data, with suggestions for fixing the issues.

Can it handle large hex strings?

Yes, DevHelper efficiently processes large hex strings and binary data. The tool is optimized for performance while maintaining accuracy in conversion and validation.

Does it support Unicode characters?

Absolutely! When using UTF-8 or UTF-16 encoding, DevHelper fully supports Unicode characters including emojis, international scripts, and special symbols.

Is this the same as Base64 encoding?

No, hex encoding and Base64 are different. Hex uses 0-9 and A-F characters to represent binary data, while Base64 uses a larger character set. Hex is more readable for debugging binary data.
