Hello, my collection includes Japanese music and sometimes non-latin characters in filenames. The playback never starts with these files.

I'm posting the data I managed to collect for a faulty file named "02 KEY - 夢の跡.flac". Database entry seems to be correct.

The problem appears to be in avconv conversion command. Here is what seems to be running (collected with ps aux | grep avconv), some characters are missing.

sh -c avconv -i '/media/ssd/Music/Various Artists/Kanon ORIGINAL SOUNDTRACK/02 KEY - .flac' -threads 4 -c:a libvorbis -q:a '8' '/var/www/sonerezh/app/tmp/20170121103828.ogg' 2>&1

I'm using PHP 5.6.29.

The foundamental issue might be with escapeshellarg function.

Someone suggested to setlocale(LC_CTYPE, "en_US.UTF-8") before calling escapeshellarg, but it didn't work for me. I also tried with other locales and the only one that worked was setlocale(LC_CTYPE, 'C.UTF-8') as suggested here.

Here are some tests on my installation.

<?php
$initialLocale = setlocale(LC_CTYPE, 0);

echo "Current Locale: " . setlocale(LC_CTYPE, 0) . "\n";
echo escapeshellarg("02 KEY - 夢の跡.flac") . "\n\n";

setlocale(LC_CTYPE, 'C.UTF-8');
echo "Current Locale: " . setlocale(LC_CTYPE, 0) . "\n";
echo escapeshellarg("02 KEY - 夢の跡.flac") . "\n\n";

setlocale(LC_CTYPE, $initialLocale);
echo "Current Locale: " . setlocale(LC_CTYPE, 0) . "\n";
echo escapeshellarg("02 KEY - 夢の跡.flac");

Current Locale: C
'02 KEY - .flac'

Current Locale: C.UTF-8
'02 KEY - 夢の跡.flac'

Current Locale: C
'02 KEY - .flac'

I patched my local installation with setlocale(LC_CTYPE, 'C.UTF-8'); before passthru($avconv…); calls in SongsController.php and it seems to have solved this problem in my situation. I guess all escapeshellarg should be patched and locale should be restored after each call. Or maybe there could be a better approach?

Thanks for this wonderful project and I hope to have been useful with this report.
