java.lang.Objectorg.openjena.atlas.io.BlockUTF8
public class BlockUTF8
Convert between bytes and chars, UTF-8 only. This code is just the UTF-8 encoding rules - it does not check for legality of the Unicode data. The standard codec do, so do not round-trip with binary compatibility. (Example: a single element of a surrogate pair will be encoded/decoded without lost. The usual Charset encoders/decoders can be expensive to start up - they are also not thread safe. Sometimes we want to convert 10's of chars and UTF-8 can be done in code with no lookup tables (which, if used, are cache-unfriendly). This code is thread safe. It uses code in the hope that JITting will make it fast if used heavily.
