Abstract:

Typographically, the Euro symbol had a difficult birth. Instead of defining a currency symbol, the European Commission dictated a logo. The inclusion of the character in computer fonts is being delayed. Both copywriters and designers struggle with inadequate solutions. The five-year history of the Euro mark, or: How typeface designers and corner-store owners restore the health of a character.
