Re^2: How to stat a file with a Unicode (UTF16-LE) filename in Windows?

It is working well. Now I understand why I was not able to stat(). I did not use Symbol, and gensym(). I will read about them. Also, in Windows, internally, which encoding is used for filenames? UTF16-le or UCS-2le?

Thanks again for sparing your time and for the great code that you have posted.

Also, in Windows, internally, which encoding is used for filenames? UTF16-le or UCS-2le? It is my tenuous understanding that the difference between UTF-16 and UCS-2 is UTF-16 can address characters above 64K and UCS-2 cannot. I haven't seen any support for multi-word characters in Windows, so I believe it's UCS-2. In practice, it doesn't matter which one you use. I did not use `Symbol`, and `gensym()` The documentation for `OsFHandleOpen` clearly defines what is acceptable, and an undefined lexical isn't one one of those.	[reply] [d/l] [select]

For what it is worth (not much) the MSDN says the following: Windows stores the long file names on disk in Unicode. ...The valid character set for these long file names is the NTFS character set, less one character: the colon (':') ... I have searched high and low for a definition of "the NTFS character set" but could not find a thing. The MSDN also offers conventions (like the Pirate's code) for naming files: Use any character in the current code page for a name, except characters in the range 0 through 31 or any character explicitly disallowed by the file system. A name can contain characters in the extended character set (128–255). However, it cannot contain the following reserved characters: < > : " / \ \| This implies single byte characters, which contradicts that above. The phrase "any character explicitly disallowed by the file system" is wonderful when they do not seem to define what they might be.	[reply]
