Merge "Update TEST_MAPPING" am: cad1f726a8 am: bb6fa3c792 am: 22b87a81e0 am: c2da52e2c5 am: f5a058e8c5 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/cesu8/+/2125833 Change-Id: I5a4837b812e7a29414185cab14ffd616b1accdf7 Signed-off-by: Automerger Merge Worker <[email protected]>
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.
