+### Encoding
+You can pick one of these values for encoding:
+*  `ISO-8859-1`
+*  `ISO-8859-2` 
+*  `ISO-8859-3`
+*  `ISO-8859-4`
+*  `ISO-8859-5`
+*  `ISO-8859-6`
+*  `ISO-8859-7`
+*  `ISO-8859-8`
+*  `ISO-8859-9`
+*  `ISO-8859-10`
+*  `ISO-8859-11`
+*  `ISO-8859-12`
+*  `ISO-8859-13`
+*  `ISO-8859-14`
+*  `ISO-8859-15`
+*  `ISO-8859-16`
+*  `Shift_JIS`
+*  `windows-1250`
+*  `windows-1251`
+*  `windows-1252`
+*  `windows-1256`
+*  `UTF-16BE`
+*  `UTF-8`
+*  `US-ASCII`
+*  `GBK`
+*  `EUC-KR`
+
+If you use a barcode scanner you can have some troubles while reading the generated QR codes. Depending on the encoding you chose you will have an extra amount of data corresponding to the ECI block. Some barcode scanner are not programmed to interpret this block of information. For exemple the ECI block for `UTF-8` is `000026` so the above exemple will produce : `\000026Life is too short to be generating QR codes`. To ensure a maximum compatibility you can use the `ISO-8859-1` encoding that is the default encoding used by barcode scanners.

 ## Readability
 
 The readability of a QR code is primarily determined by the size, the input
