Snap for 13873778 from 6ad5cf49208d543508858996f76dd09e942ccb33 to internal-android15-automotiveos-lts-release Change-Id: Ie6737062c09f34fd792f0e1fde6e6c0e466bf73b
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.
