@ -428,10 +428,21 @@ The --binary option prevents Zint from performing any convertion of the data
before placing in the barcode symbol and should be used if you are encoding raw
binary or encrypted data.
If you are using data from file which is not UTF-8 formatted then you can
specify the encoding by using the --eci= switch followed by the appropriate number
from the table below. This procedure adds an ECI flag in the barcode data which
tells the barcode reader to change character encoding.
If your data contains non ISO-Latin-1 characters, you may encode it using an ECI-aware
Symbology and an ECI value from the table below.
The ECI information is added to your code symbol as prefix data.
The ECI-Value may be specified with the --eci switch, followed by the value in the column
"ECI Code".
The first row of the table (ECI code 3) is the default value and does not lead to any ECI
information included into the symbol.
The input data should be utf-8 formatted. Zint automatically translates the data into the
target encoding.
The rows marked with a star (*) do not do this transformation. The data must be specified
as binary data (--binary switch) with the data in the encoding given by the "Character
Encoding Scheme" column.

--------------------------------------------------------
* Note: When using the ECI flag Zint will treat all input data as raw binary.
This means that data which is encoded using a multiple-byte encoding schemes
(other than UTF-8) will not use optimal compression. It is therefore
recommended that data using these schemes be converted to UTF-8 using iconv
or similar before passing it to Zint.
Two examples:
Ex1: The Euro sign should be encoded in ISO-8859-15.
The Euro-Sign has the ISO8859-15 codepoint hex A4.
It is encoded in utf-8 as the hex sequence: e2 82 ac
Those 3 bytes are contained in the file "utf8euro.txt"
This command will generate the corresponding code:
zint.exe -b 71 --square --scale 10 --eci 17 -i utf8euro.txt
Ex2: The Chinese character with Unicode codepoint hex 5e38 should be
encoded in big5 encoding. The big5 ECI is marked in the upper table to
require input data in big5 instead of utf-8. The big5 representation of
this character are the two hex bytes: 9c 75 (contained in the file big5char.txt).
The generation command is:
zint.exe -b 71 --square --scale 10 --eci 28 --binary -i big5char.txt
