I think I may have a "workaround" to somehow solve this Unicode problem. I have the idea in my mind, but it's hard to explain, but I'll try my best. I will need direct interaction of Rejetto. First, I need to know some internal things about HFS. So, this is my first question:

- Is HFS able to internally "read" any file with unicode characters?. When I say "read", I mean read the file at low level, no matter the file name.

file handling is not a problem,
even if the support was not full on that, it could be easily done

Well, in that case, my idea may work. I've discovered that some servers send the file name, after the download has started. So, I thought that this can solve the "unicode problem" once and for good.

For example, you may add an option (to users with unicode problems), to generate and use generic URLs, instead of using URLs with the file name embedded. For example:

Code: [Select]
Instead of this:
http://myserver.com/folder1/folder2/file123.rar
http://myserver.com/folder52/folder62/file123.rar

Give something like:
http://myserver.com/download/333445289345343 (some random number)
http://myserver.com/download/845600032348881 (some random number)

...and when the download starts, send the real file name (file123.rar)

I've seen this in a lot of servers. For example, when you download a subtitle from addic7ed.com, this is exactly what happens.


Here is the addic7ed.com example.
The URL was:
Code: [Select]
http://addic7ed.com/original/88150/1and when the download has started, it automatically sends
the real file name: "Chicago PD - 01x14 - The Docks.LOL.English.HI.C.orig.Addic7ed.com.srt"

If you need another example to analyze, just ask me.

Do you think this can fix the problem and make HFS unicode compatible?... :)

It's not only about URL encoding, it's more about how HFS talks to the download client, when the download starts.

Yes, well, personally I really don't need to have unicode support at all, but I think it will help a lot of people around the world. I'm just trying to give ideas to make HFS better, because I think it's great, and may be this can give the users another way to handle unicode files. I hope this helps...

sorry but that's not the problem i have with HFS 2 and unicode.
It's all about the GUI, not the networking part, not the file handling.
HFS 3 already handles unicode correctly. Sad is that i don't have enough time to make it complete.
