/**

* Set of CharsetEncoders for a given input string

|
* Invariants:
|
* - The list contains only encoders from CharacterSetECI (list is shorter then the list of encoders available on
|
* the platform for which ECI values are defined).
|
* - The list contains encoders at least one encoder for every character in the input.
|
* - The first encoder in the list is always the ISO-8859-1 encoder even of no character in the input can be encoded
|
* by it.
|
* - If the input contains a character that is not in ISO-8859-1 then the last two entries in the list will be the
|
* UTF-8 encoder and the UTF-16BE encoder.
