Try to use urlencode to encode your directory name:

$str = 'c:\\'.urlencode('表').'\t.txt';
$con=file_get_contents( $str);
echo $con;

This is described here in detail.

EDIT

Assuming you're using UTF-8 encoded source files, you could also try one of the following

$str = 'c:\\'.urlencode(mb_convert_encoding('表', 'UTF-16', 'UTF-8')).'\t.txt';
// or just
$str = 'c:\\'.mb_convert_encoding('表', 'UTF-16', 'UTF-8').'\t.txt';

As far as I know newer (> FAT32) Microsoft filesystems use UTF-16 encoding. But this will make your solution fail on other (e.g. Linux) filesystems.

EDIT 2

You can also try to convert your UTF-8 filename into a different encoding such as SJIS, SJIS-win, SJIS-2004, JIS, EUC-JP, eucJP-win, EUC-JP-2004, CP932, JIS-ms or the like. But I'm not an expert in east asian character encodings - so treat that information with caution.

try this

<?PHP
$con=file_get_contents('./表/t.txt', true);
$con=file_get_contents('./表/t.txt',FILE_USE_INCLUDE_PATH);

echo $con;
?>

Language : PHP

$results = scandir('c:\');
$result will give you all folder name inside c drive.
you can find your folder in $result array.
now you have folder name in $result and now you can go to file.

Modified : 

$results = scandir('/web');
$results = "/web/$results[21]/t.txt";
$con=file_get_contents( $results);
echo $con;

Explanation :

1.) /web is the directory where is  表 folder and some other folders.
2.) $result[21] is giving me value 表 on browser i know its 表 folder.
3.) Now you have file path. Go ahead.

NOTE : If you still use Chinese character in your folder and file then you have to change your OS from window to ubuntu.

Create path based on single /

$content = file_get_contents("C:/表/t.txt");
