Frequently asked questions

Character sets and representations

Convert URL, Base64, HTML entities, Unicode escapes or hexadecimal bytes. Byte conversion supports UTF-8, UTF-16 LE/BE, ASCII and ISO-8859-1 in both directions.

Loss and storage

Unrepresentable characters fail without substitutions. Byte order is explicit and BOMs are not added or removed automatically.
