In the java.nio.charset.Charset description, there are some inaccurate
definitions.

  - "a charset is defined as the combination of a coded character set and
    a character-encoding scheme" assumes one coded character set. But it
    should be one or multiple coded character sets.

  - "full Unicode, which is the same as ISO 10646-1" is not accurate. They
    are not the same thing as Unicode.org says. If it means only in the
    context of a coded character set, the description should clarify the
    revisions.

  - In "A character-encoding scheme is a mapping between a coded character
    set and a set of octet (eight-bit byte) sequences.", "a coded character
    set" should be "a coded character set or several coded character
    sets" as defined in RFC 2278. The examples clarify it, though.

  - "Some schemes, however, are associated with multiple character sets;
    EUC, for example, can be used to encode characters in a variety of
    Asian character sets." should be "Some schemes, however, are
    associated with multiple coded character sets; EUC, for example, can
    be used to encode characters in a variety of Asian coded character
    sets."
