I think the problem is in the data.frame code, not in writing. 
Data.frames try to display things in a readable way, and since you're on 
Windows where UTF-8 is not really supported, the code helpfully changes 
that character to the "<U+1E21>" string. for display.

You should be able to write the Unicode character to file if you use 
lower level methods such as cat(), on a connection opened using the 
file() function with the encoding set explicitly.
