* Aztec encoder: add ECI codes according to character set
Added redundant methods to avoid modifying existing tests.
* fix testAztecWriter
- ISO-8859-1 cannot actually encode Euro symbol ('€'); this test case only
passed before because the Decoder wasn't actually doing the bytes→String
decode, but simply round-tripping an unknown byte.
- Add extra test cases for implicit ISO-8859-1 (without ECI code), explicit
ISO-8559-1 (with ECI code), and Shift_JIS
* remove unnecessary conversion between String and byte[] in Aztec EncoderTest and DetectorTest
* Aztec DecoderTest: use constants for charsets
* Aztec Code: remove unnecessary conversion between Charset and Charset.name() strings
* PDF417, QR, DataMatrix: remove unnecessary conversion between Charset and Charset.name() strings
Includes replacing StringUtils.guessEncoding() with .guessCharset(), to return
Charset rather than String.
This change makes the tacit assumption that Shift_JIS charset *will* be
available. There are existing comments suggesting that it might not always
be available… but the existing *tests* assume it will be.

Project in Maintenance Mode Only
The project is in maintenance mode, meaning, changes are driven by contributed patches. Only bug fixes and minor enhancements will be considered. The Barcode Scanner app can no longer be published, so it's unlikely any changes will be accepted for it. There is otherwise no active development or roadmap for this project. It is "DIY".
Get Started Developing
To get started, please visit: https://github.com/zxing/zxing/wiki/Getting-Started-Developing
