|
|
* of |nsILocalFile|) is UTF-8 or not. Knowing that helps us avoid an

|
* name in UTF-8 out of nsILocalFile, we can just use |GetNativeLeafName| rather
|
|

|
|
* On Unix (but not on Mac OS X), it depends on the locale and is not known
|
|
* in advance (at the compilation time) so that this function needs to be

|
* a real function. On Mac OS X and BeOS, it's always UTF-8 while on Windows
