Abstract:

How will the character be inserted into typeset copy? Every time typesetters set a piece containing a monetary amount in Euros, they will have to type a character that doesn't exist in most typeface character sets. A partial remedy is the inclusion of a Euro character in the character set of Macintosh and Windows. For instance, starting in Mac OS 8.5, pressing Option-Shift-2 will insert the Euro character — but only in the fonts that come with the Mac. Older fonts will insert a different character.
