Production Euro Symbol with Groff 1.18

[Yair Lenga]

Good Afternoon,

I'm trying to produce 'Euro' symbol with Groff-1.18. I'm using the 
following simple input file:

      $        \[Do]   dollar
      c        \[ct]   cent
      Y        \[Ye]   yen
      e        \[Eu]   Euro             Euro Currency
      e        \[eu]   Euro             Euro Currency
      L        \[Po]   sterling         British currency sign
      x        \[Cs]   currency         Scandinavian currency sign
      f        \[Fn]   florin           Dutch currency sign

and the command line:

/usr/local/groff-1.18/bin/groff 1 > 1.ps

I'm getting:
1:4: warning: can't find special character `Eu'
1:5: warning: can't find special character `eu'

I'm using "plain" build of groff 1.18, on SunOS 5.8.

Any help will be appreciated.

Yair
