Hi,
I'm having a problem right now. Some of our French users uploaded some files with file names that had French accent marks, and those file names were inserted into the Postgres database. When I examined the value of those file names, they all had some weird characters (the weird characters were in the same position where the accent marks were entered). I do not know how to handle this kind of situation. Most of my users are US based, but I have been told that there will be more international users in the future.
So my questions are:
(1) What is the best character encoding that would work for most of those languages that have accent marks?
(2) I assume that I also need to do some kind of conversion in the front end (PHP) as well.
I'm running on Linux and Postgres 8.3.8.
Any ideas?
Thanks in advance.

Hi,
our solution for storing uploaded files in database/filesystem with php uses utf-8 for the filenames in the database in combination with string-replacement for some special characters in php. These are in our case the german "Umlaute" (ä,ö,ü,ß), because otherwise we get the problem of strange translations of these characters (php uses utf-8, german windows uses cp-1250), that made them unusable for download-links. You can use the function below, just add your special characters to the $trans-array. As another benefit this function returns unique filenames that can be used for storing the files in a target-directory.
<SNIP>
public static function get_unique_file_name($target_dir, $current_file_name){
$trans = array ("ä" => "ae", "ö" => "oe", "ü" => "ue", "ß" => "ss", "Ä" => "Ae", "Ö" => "Oe", "Ü" => "Ue");
target_file_name = strtr($current_file_name, $trans);
$i = 0;
$old_target_file_name = $target_file_name;
while(file_exists($target_dir . '/' . $target_file_name)){
$i++;
$target_file_name = $i . $old_target_file_name;
}
return $target_file_name;
}
</SNIP>
