Embed euro symbol htmlText won't work. Result is small box. Font arial bold. Euro symbol is included in special characters (embed menu)

I want to output txt files in html format. Everything works as it should, only the euro symbol will not show.  I want htmlText, because this way I can underline some parts of the text, make color changes ect. ect. I cannot output the euro symbol. I've tried embedding but with no result.
