Migrate to cargo_embargo. am: 2b68c7ca5a am: c7bc62421e am: c42d3ceb5f Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/cesu8/+/2822395 Change-Id: I85a94a0bdfdacde30d9282d181e2453b0cd7af09 Signed-off-by: Automerger Merge Worker <android-build-automerger-merge-worker@system.gserviceaccount.com>
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.
