[NTG-context] How to access special quotationsmarks and the euro symbol

Hi all, can anyone tell me how the following unicode characters can be accessed with ConTeXt? “ - left double quotation mark „ - double low 9 quotation mark In LaTeX I used the \grqq- and \glqq-macros. In addition, I have difficulties in accessing the Euro character. The proposed method \usesymbols[euro] and the later use of \euro or \texteuro does not work. I get the message \definedfont=eurose at 14.39996pt not loadable: Metric (TFM) file not found. What steps do I have to perform in order to install that font correctly? Thanks for your attention and effort, --Stefan
