getDefaultCharacterSet
public static Charset getDefaultCharacterSet()
- Return the default character set, which is UTF-8, but could in
principle change.
- Returns:
- a static Charset object
charsetFromString
public static Charset charsetFromString(java.lang.String charsetName)
- Converts a character set name to a Charset. If the input name
is null, then return the default Charset. If the input name
does not correspond to a legal or supported
character set, then return the default Charset and give a warning.
- Parameters:
charsetName - the name of a putative character set, or null
- Returns:
- the Charset corresponding to the argument, or the
default character set (see
getDefaultCharacterSet()) if
that is not possible
