Update files_texteditor/ajax/loadfile.php

The problem was, that loadfile.php (the file text-editor) did not correctly load Windows ANSI / ISO encoded files.

After much research I found a solution:

You have to specify the possible encodings when calling mb_detect_encoding. Then the detection works. Possibly an error in PHP.

You can list all implemented encodings with mb_list_encodings(). In the above code-change we construct a string suitable for mb_detect_encoding with the implode function.

Believe it or not (better try it): Without the modification, the text-editor does not display Windows-ANSI files correctly, with the modification, it does ;-)

It also recognizes UTF with BOM and without BOM and all other implemented encodings!

With this short commandline PHP code you can test it:.

<?php

// read file specified on command line
$fd = fopen($_SERVER['argv'][1],"r");
$s = fread($fd,10000);
fclose($fd);

// this prints correct encoding for Windows ISO file
echo mb_detect_encoding($s,implode(", ",mb_list_encodings())) . "\n";

// this prints wrong encoding for Windows ISO file
echo mb_detect_encoding($s) . "\n";

?>
