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

|
* unncessary encoding conversion in some cases. For instance, to get the leaf
|
|
* name in UTF-8 out of nsILocalFile, we can just use |GetNativeLeafName| rather
|
|
* than using |GetLeafName| and converting the result to UTF-8 if the file
|
|
* system encoding is UTF-8.
|
|
* 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 it's always UTF-8 while on Windows
|
|
* and other platforms (e.g. OS2), it's never UTF-8.
