Frequently Asked Questions
Are UTF-8 and special international characters supported without corruption?
Yes. Unlike naive browser implementations, our engine handles multibyte UTF-8 byte streams properly, guaranteeing zero character corruption for all languages and emojis.
Is Base64 considered encryption?
No, Base64 is a binary-to-text encoding scheme, not an encryption method. It provides zero cryptographic secrecy and can be decoded by anyone.
