It is not even dependent on the particular device. The euro comes from the 
ninth glyph in the TR font, so it depends on the particular font encoding. The 
glyph numbering is specified in the file text.enc, so you can have your own 
glyph order if desired. So not really an oops, just not what you might have 
expected.
