[oXygen-user] copyright symbol not from Alegreya font but from Arial

Hi, I had this already solved, but after a hard disk crash I have to do it again: My text (a copyright marker on the second page after the title page) shows the symbol as arial while the proper symbol of the Alegreya font is present on the desktop. the one in the pdf the same in inkscape. Which paramater do I have to change to get the proper symbol of the font? Regards Bernhard
