Snap for 9719949 from bf620bb5f2fbd519dc45100da7edcd62db4b756f to udc-release Change-Id: I16f2ae0a1439e309239bc24b77bcdffc636f43e2
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.
