//
// At the moment following values for this property are supported, property
// value string is case insensitive.
//
// (1)"Windows-31J/Shift_JIS"
// In 1.4.1 we added a correct implementation of the Shift_JIS charset
// but in previous releases this charset name had been treated as an alias
// for Windows-31J, aka MS932. Users who have existing code that depends
// upon this alias can restore the previous behavior by defining this
// property to have this value.
//
// (2)"x-windows-50221/ISO-2022-JP"
// "x-windows-50220/ISO-2022-JP"
// "x-windows-iso2022jp/ISO-2022-JP"
// The charset ISO-2022-JP is a "standard based" implementation by default,
// which supports ASCII, JIS_X_0201 and JIS_X_0208 mappings based encoding
// and decoding only.
// There are three Microsoft iso-2022-jp variants, namely x-windows-50220,
// x-windows-50221 and x-windows-iso2022jp which behaves "slightly" differently
// compared to the "standard based" implementation. See ISO2022_JP.java for
// detailed description. Users who prefer the behavior of MS iso-2022-jp
// variants should use these names explicitly instead of using "ISO-2022-JP"
// and its aliases. However for those who need the ISO-2022-JP charset behaves
// exactly the same as MS variants do, above properties can be defined to
// switch.
//
// If we need to define other charset-alias mappings in the future then
// this property could be further extended, the general idea being that its
// value should be of the form
//
// new-charset-1/old-charset-1,new-charset-2/old-charset-2,...
//
// where each charset named to the left of a slash is intended to replace
// (most) uses of the charset named to the right of the slash.
