There is no “ANSI encoding“.  Usually “ANSI encoding” means Windows-1252. 
[0]  It would be either coincidence or strange if this worked, because FAT32 
uses the “OEM character set”, i. e. one of the various IBM code pages, 437 
for English, and NTFS uses UTF-16BE [1].  The letter “è” has Windows-1252 
code 0xE6, IBM437/IBM850 code 0x8A, and Unicode code point U+00E8 [2] 
(encoded in UTF-16 as 0xE8 [3]).  It follows that you cannot mean 
Windows-1252 by “ANSI”.

The file, or the string?

Yes, it is, but only with NTFS.

Which cannot work with NTFS.

But only with NTFS and compatible filesystems.
