Perl treats file names as opaque strings of bytes. That means that file names need to be encoded as per your "locale"'s encoding (ANSI code page).

In Windows, code page 1252 is commonly used, and thus the encoding is usually cp1252.* However, cp1252 doesn't support Tamil and Hindi characters.

Windows also provides a "Unicode" aka "Wide" interface, but Perl doesn't provide access to it using builtins**. You can use Win32API::File's CreateFileW, though. IIRC, you need to still need to encode the file name yourself. If so, you'd use UTF-16le as the encoding.

Aforementioned Win32::Unicode appears to handle some of the dirty work of using Win32API::File for you. I'd also recommend starting with that.

* — The code page is returned (as a number) by the GetACP system call. Prepend "cp" to get the encoding.

** — Perl's support for Windows sucks in some respects.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
