Examples of Utf8

com.datasalt.pangool.io.Utf8
Main String type for Pangool. Natively supported.
net.nutch.io.UTF8
A WritableComparable for strings that uses the UTF8 encoding.
Also includes utilities for efficiently reading and writing UTF-8. @author Doug Cutting
org.apache.avro.util.Utf8
A Utf8 string. Unlike {@link String}, instances are mutable. This is more efficient than {@link String} when reading or writing a sequence of values,as a single instance may be reused.
org.apache.hadoop.io.UTF8
A WritableComparable for strings that uses the UTF8 encoding.
Also includes utilities for efficiently reading and writing UTF-8. @deprecated replaced by Text
org.apache.harmony.archive.internal.pack200.ConstantPoolEntry.UTF8
TODO Comment -- quite a lot can be nicked from Codec, since this was created from it @author Alex Blewitt
