Curiously, I was not able to find any method to get the real number of  
bytes required to store the string. There is  
CFStringGetMaximumSizeForEncoding, which usually returns a number much  
larger than actually required. And then there is CFStringGetLength, which  
is useless to determine the storage size for a variable length encoding.

Indeed, all these solution a rather ugly. Any hint from Mac developers on  
how to implement this correctly?

CFStringGetCStringPtr() always returned NULL in all my tests.


Thanks!
