I thought the data.frame function didn't alter the unicode coding,
since funny.g$funny.g above still displays the right unicode character
(although it does list the levels as <U+1E21>).

I'm sorry, but I don't understand what it means "to use cat() on a
connection opened using the file() function". Could you please clarify
