CESU-8 encoder/decoder for Rust

Build Status Latest version License

Documentation.

Convert between ordinary UTF-8 and CESU-8 encodings.

CESU-8 encodes characters outside the Basic Multilingual Plane as two UTF-16 surrogate chacaters, which are then further re-encoded as invalid, 3-byte UTF-8 characters. This means that 4-byte UTF-8 sequences become 6-byte CESU-8 sequences.

Note that CESU-8 is only intended for internal use within tightly-coupled systems, and not for data interchange.

This encoding is sometimes needed when working with Java, Oracle or MySQL, and when trying to store emoji, hieroglyphs, or other characters on the Supplementary Multilingual Plane or the Supplementary Ideographic Plane.
