Str_getcsv broken, clicks of diacritics?

Question

I have this code in a UTF-8 encoded file:

<?php setlocale(LC_ALL, 'cs_CZ.utf8'); //Can be commented out without effect. $input = "Štěpán,Šafránek"; $result = str_getcsv($input); echo $result[0]; //output = "těpán"; echo $result[1]; //output = "afránek"; ?> 

Notice the trimmed lines that cause echoes.

It also works:

 <?php setlocale(LC_ALL, 'cs_CZ.utf8'); //Can be commented out without effect. $input = "aaaŠtěpán,aaaŠafránek"; $result = str_getcsv($input); echo $result[0]; //output = "aaaŠtěpán"; echo $result[1]; //output = "aaaŠafránek"; ?> 

Since the input line is part of the script, there should be no encoding problems, right? The language is installed correctly, right?

So what's wrong? My solution is that str_getcsv () is just broken. Any alternative way to parse CSV?

Interestingly, on Windows, this works great, but on Linux, I see this behavior.
