it seems you have to output Char(128) HEX 80, to the serial device and it should show
i modified the ASCII sample that comes with the IDE to print all from 0 - 255 so it will include the euro symbol
/*
ASCII table
Prints out byte values in all possible formats:
* as raw binary values
* as ASCII-encoded decimal, hex, octal, and binary values
For more on ASCII, see http://www.asciitable.com and http://en.wikipedia.org/wiki/ASCII

void setup() {
//Initialize serial and wait for port to open:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for Leonardo only
}
// prints title with ending line break
Serial.println("ASCII Table ~ Character Map");
}
// modified to start with 00 even though some of these may be unprintable:
int thisByte = 00;
// you can also write ASCII characters in single quotes.
// for example. '!' is the same as 33, so you could also use this:
//int thisByte = '!';
void loop() {
// prints value unaltered, i.e. the raw binary version of the
// byte. The serial monitor interprets all bytes as
// ASCII, so 33, the first number, will show up as '!'
Serial.write(thisByte);
Serial.print(", dec: ");
// prints value as string as an ASCII-encoded decimal (base 10).
// Decimal is the default format for Serial.print() and Serial.println(),
// so no modifier is needed:
Serial.print(thisByte);
// But you can declare the modifier for decimal if you want to.
//this also works if you uncomment it:
// Serial.print(thisByte, DEC);
Serial.print(", hex: ");
// prints value as string in hexadecimal (base 16):
Serial.print(thisByte, HEX);
Serial.print(", oct: ");
// prints value as string in octal (base 8);
Serial.print(thisByte, OCT);
Serial.print(", bin: ");
// prints value as string in binary (base 2)
// also prints ending line break:
Serial.println(thisByte, BIN);
// if printed last visible character '~' or 126, stop:
if (thisByte == 255) { // modified to go all the way to 255
// This loop loops forever and does nothing
while (true) {
continue;
}
}
// go on to the next character
thisByte++;
}
Your routine that is called print() always puts a new line before it exits therefor your euro symbol will always be on a new line. remove this from the print routine and put the newline statements elsewhere if you need them
Serial.println vs Serial.print, the first one adds a new line before executing the next line so again adding a new line before you get to send the euro symbol, the second version does not so change your statement to the second version
The other stuff is because your talking to your PN532 on the same serial as the console, or atleast that is what it seems so when you do things like sendTX(...) it will show up on the console, as this is not really printable ascii it looks like gobbledygook
Provide your wireing schematic and or a link to the exact product your connecting and I can probably help further, I am assuming your using one of the ADAFRUIT boards but you dont say and are not showing any libraries so im guessing
