| | Write a euro symbol to output stream
Please Login to Remove!
I'm sending some strict CPCL commands to a label printer via Bluetooth serial port to produce a printed 'receipt'.
Every line I send to the device I have to convert to bytes and then use _dout.write(bytes, ind begin, ind end) as otherwise 2 byte characters get written to the output stream and the printer doesn't understand them - pretty much every character is prefixed with the ASCII 00 character/byte...
I now have a problem where, when attempting to write a euro symbol tot he output stream I'm getting simply a '?' in place of the euro symbol. I'm using string.getBytes() to do the conversion from string to byte array.
I have taken a raw dump of the input to the printer and see that the character that gets written is the ascii char 3F which is the '?' I'm seeing in the printer so the problem must occur before the data is sent to the output stream.
