Description:
In this old bug report http://bugs.mysql.com/bug.php?id=43184 the conclusion was wrong as regards LOAD DATA LOCAL INFILE.

Docs were updated to read
"On Windows, MySQL Server supports only directory and file names that are compatible with the current ANSI code pages. 
..
The same limitation applies to directory and file names referred to in SQL statements, such as the data file path name in LOAD DATA INFILE."

However, LOAD DATA LOCAL does not even support non-ASCII characters *INSIDE* current ANSI code page.

How to repeat:
With a 'Western' locale setting execute LOAD DATA LOCAL INFILE with an existing and valid data file named 'æøå.csv' as parameter (or use German umlauts or Spanish ñ etc. in filename)

The error "file not found" is returned. 

Letters 'æøå' definitely belongs to current ANSI code page here as my LOCALE setting is Danish!

Suggested fix:
No idea.

Maybe the CLI looks for a file with utf8-encoding of the characters.  If so it would also be reproducible on 'big endian utf16' systems (Mac etc.). And even worse: there is a small chance that such file actually exists and the statement may then load data from another file than expected.

Thank you for the bug report.
