FAQ
What is Base32?
Base32 is an encoding defined by RFC 4648 that represents binary data using 32 characters (A-Z and 2-7), commonly used where case-insensitive data transfer is needed.
Does it support Chinese?
Yes. Text is first encoded as UTF-8 bytes before Base32 conversion, so Chinese, emoji and any characters are encoded and decoded correctly.
What format tolerance does decoding offer?
Decoding tolerates lowercase letters, missing = padding and spaces; invalid characters outside the alphabet produce a clear error message.
