Will foo_unpack work with utf-8 filenames ?


I have found that foobar2000 can't read mp3 files within some particular ZIP archive (however those mp3 file will be readable when be archived with RAR format)
I have noticed those archive files using utf-8 filenames, so my question is that - will foo_unpack  work with utf-8 filenames ?

Thank in advance!

One of foobar2000 features is full unicode supported, no matter it is unicode big endian, utf-8 etc.
If your files are about Asian characters, then you will need to install these characters from your original OS cd.
Chinese characters can use unicode add-on which is called Unicode-At-on.

eddy@, thank for your reply.

But I didn't mean CJK glyphs should be displayed on  my monitor! I mean those zip archived .mp3 files should be play when their utf-8 filenames !

Could anyone's foo_unpack read the .zip at http://ifile.it/976uwkp ?
Thank in advance.

It reads it, but it turns the filename into a jumble of ANSI garbage. The file will still play, as long as the filename matches what the archive contains.

Thank for kode52's reply, I realized that  ANSI code page  of my configuration is 950 and I found that
if I change the language for non-Unicode program to English, the problem is gone.

But if the language for non-Unicode program is Chinese, foo_unpack can't read the content! Will it to be consider as a bug ?

thank

Sorry for misunderstanding.
Open your file with Windows' compressed (zipped) folder is empty, but with Winrar is normal.
If I extract the file and use Winrar 3.92 Eng. version to make a zip archieve again, foobar2000 can play the archive file.
If I use Winrar 3.70 Cht. version, Winrar can not even extract the file.
It seems that this is not a bug of foobar2000.
My OS language is Chinese traditional. This situation never happens to me.
I don't know much, but the archieve software you are using might be the solution.

I had tried info-Zip, WinRAR (3.91), 7-Zip and Winzip but all of them give the same result.

Could you provide the .zip you said which is correct ? (Maybe you replaced your current Codepage with some custom mapping? )

Thank in advance.

Sure.

The filename byte sequence within the .zip that you provided  is

C7 AF C7 AF C7 E9 C7 55 20 B8 F1 2E 6D 70 33


I think the filename string isn't encoded with utf-8. 

(the UTF-8 byte seq of "?????"  is
E3 82 B3 E3 82 B3 E3 83 AD E3 81 AE E8 B7 A1)

What? I didn't touch the extracted filename.
If it is encoded by UTF-8, then to extract and recompress it must be UTF-8, right?

I think the reason is that your current ANSI code page can be used to encode the filename.
And I think you are using WinRAR.

This behavior is documented at http://www.rarlab.com/rarnew.htm

"
Added support for ZIP archives containing Unicode file names in UTF-8 format. When creating ZIP archive, WinRAR stores names in Unicode only if they cannot be stored correctly using the current single byte character set. "


The problem seems was narrowed to if my current ANSI codepage can't encode the filename, then the file can't be read.

I think it is not bad to summary the GOOD scenario .

1. My Windows configuration chooses Codepage 950 as my ANSI code page
2. The filen within the unreadable archive is "ココロの跡.mp3" encoded with utf-8 , "ココロの跡" in unicode is u30B3 u30B3 u30ED u306E u8DE1
3. Codepage CP950 (See http://unicode.org/Public/MAPPINGS/VENDORS...DOWS/CP950.TXT) can't encode u30B3, u30ED,u306E those Katakana letters.

After some google swarming, I realized that utf-8 filename is documented at http://www.pkware.com/documents/casestudies/APPNOTE.TXT. (It is called as an application note but some people call it as PKWARE specification)

Finally, I question is that - will foo_unpack work with utf-8 filename (or it is compatible with Unicode )?

Thanks in advance!
