Hi Klaus,

HTMLtext is no good, because the ¤ entity, while Rev correctly  
renders it as a Euro sign on the Mac, on Windows it produces a generic  
currency sign.

That leaves us with unicode. The code point for the Euro sign is hex  
0x20AC, which is decimal 8364. Usually you get reliable results by  
using unicode escape entities in htmlText, but again htmlText fails  
us, because this doesn't work:

    set the htmlText of fld 1 to "<p>€"

The only reliable way I can see is UTF-8. On my Mac the UTF-8 ASCII  
equivalent string is €. But that's different on Windows, so I looked  
at the ASCII code points for the three characters. They are 226 130  
172. So I tried the following and it reliably rendered the Euro sign  
on both Mac and Windows (no Linux here for me to try, but it should  
work there, too.)

set the unicodeText of fld "euro" to \
  uniencode((numToChar(226) & numToChar(130) & numToChar(172)),"utf8")

That ought to work for you.

Regards,

Devin
