Yes -- that looks like UTF-8 encoding of the Euro character. Check if your script is saved as UTF-8 (it is, trust me on that).
To prevent your script saved as something else than plain ASCII, use Unicode notation for any characters outside ASCII range; in this case, use "\u20ac", to insert the Euro.
Great Jongware! It worked!
Also, could you tell me any resources where I can find Unicode notation?
I'm behind a Windows machine now, so I can call up "charmap", which can show the Unicode value of just about every character in every font.
Not sure for the Mac ... perhaps simply use UnicodeChecker (you can search for "Euro" using one of the menus).
Many thanks Jongware.
Mac has an OS character palette which has a lot of features including
the ability to search for characters by name...
You need to enable it in the International preference pane.
