Class Charsets

  • public class Charsets
extends java.lang.Object
    Charsets required of every implementation of the Java platform. From the Java documentation Standard charsets:

    Every implementation of the Java platform is required to support the following character encodings. Consult the release documentation for your implementation to see if any other encodings are supported. Consult the release documentation for your implementation to see if any other encodings are supported.

    US-ASCII
    Seven-bit ASCII, a.k.a. ISO646-US, a.k.a. the Basic Latin block of the Unicode character set.
    ISO-8859-1
    ISO Latin Alphabet No. 1, a.k.a. ISO-LATIN-1.
    UTF-8
    Eight-bit Unicode Transformation Format.
    UTF-16BE
    Sixteen-bit Unicode Transformation Format, big-endian byte order.
    UTF-16LE
    Sixteen-bit Unicode Transformation Format, little-endian byte order.
    UTF-16
    Sixteen-bit Unicode Transformation Format, byte order specified by a mandatory initial byte-order mark (either order accepted on input, big-endian used on output.)

    This class best belongs in the Commons Lang or IO project. Even if a similar class is defined in another Commons component, it is not foreseen that Commons Compress would be made to depend on another Commons component.
