//This sample shows how to use FNC1 first position in Extended Mode.

//Extended Channel mode which supports FNC1 first position, FNC1 second position and multi ECI modes.
//It is better to use QrExtCodetextBuilder for extended codetext generation.
//Use Display2DText property to set visible text to removing managing characters.
//Encoding Principles:
//All symbols "\" must be doubled "\\" in the codetext.
//FNC1 in first position is set in codetext as as "<FNC1>"
//FNC1 in second position is set in codetext as as "<FNC1(value)>". The value must be single symbols (a-z, A-Z) or digits from 0 to 99.
//Group Separator for FNC1 modes is set as 0x1D character '\\u001D'
//If you need to insert "<FNC1>" string into barcode write it as "<\FNC1>"
//ECI identifiers are set as single slash and six digits identifier "\000026" - UTF8 ECI identifier
//To disable current ECI mode and convert to default JIS8 mode zero mode ECI indetifier is set. "\000000"
//All unicode characters after ECI identifier are automatically encoded into correct character codeset.
