FAQ
- Does it support non-English text?
- Yes. Encoding uses UTF-8 so CJK and other Unicode characters round-trip correctly.
- What if decoding fails?
- Check that the input is a complete Base64 string without stray characters.
- Can it handle files?
- This version is for text. File encoding can be added later without changing the text flow.
