/**
* Encoder that encodes minimally
*
* Algorithm:
*
* The eleventh commandment was "Thou Shalt Compute" or "Thou Shalt Not Compute" - I forget which (Alan Perilis).
*
* This implementation computes. As an alternative, the QR-Code specification suggests heuristics like this one:
*
* If initial input data is in the exclusive subset of the Alphanumeric character set AND if there are less than
* [6,7,8] characters followed by data from the remainder of the 8-bit byte character set, THEN select the 8-
* bit byte mode ELSE select Alphanumeric mode;
*
* This is probably right for 99.99% of cases but there is at least this one counter example: The string "AAAAAAa"
* encodes 2 bits smaller as ALPHANUMERIC(AAAAAA), BYTE(a) than by encoding it as BYTE(AAAAAAa).
* Perhaps that is the only counter example but without having proof, it remains unclear.
*
* ECI switching:
*
* In multi language content the algorithm selects the most compact representation using ECI modes.
* For example the most compact representation of the string "\u0150\u015C" (O-double-acute, S-circumflex) is
* ECI(UTF-8), BYTE(\u0150\u015C) while prepending one or more times the same leading character as in
* "\u0150\u0150\u015C", the most compact representation uses two ECIs so that the string is encoded as
* ECI(ISO-8859-2), BYTE(\u0150\u0150), ECI(ISO-8859-3), BYTE(\u015C).
