Trouble parsing € with Barcode4J MessagePatternUtil

Question

I'm trying to insert a € in the Message and/or Pattern for a barcode using
org.krysalis.barcode4j.tools.MessagePatternUtil
in Barcode4J, but am just getting hieroglyphics.

Does anyone know how to do this?

Answer 1

Well, it seems MessagePatternUtil works on a byte-by-byte basis, so it can't handle multiple-byte characters like the € (Euro).

I've posted an improved version that can handle Unicode here:
