The password with foreign characters - is that extended ASCII, or UTF8? Could you post the hex dump of the input string as you're hashing it? There are a few ways some of the foreign characters can be encoded, and I'd like to work out the issues with it in my system as I revise it so it can handle foreign characters more or less properly.
Also,
http://www.insidepro.com/hashes.php?lang=eng comes up with b2d1969ce7ecf519a73d6b2f9c4f96e4 as the hash for íàòàøåíüêà - it really depends on how it's encoded.
Right now, the front end is VERY alpha - I threw it up in a few hours a while back to help with some specific needs. I'm going through and completely redoing it now, which allows individual user accounts, far better bulk uploads/downloads, user credits (so cracking formerly uncracked passwords will get you credits that can then be used for cracking things that take more time, rainbow table parts will get you credits, wordlist entries that haven't been added before will get you credits), etc.
In the initial "live" implementation, I intend for unsalted hashes to be free to crack through the brute forcers, dictionary attacks, and some of the rainbow tables (though the brute forcers & mutating dictionary attacks should catch most things). Throwing hashes at the largest rainbow tables, or running salted hashes through the system, will require credits, as these are a LOT more computationally intense (I can't run them massively in parallel, and I only have so much computing power available). This may shift as the distributed system comes online if I have a ton of CPU/GPU power I can make use of, but I'll cross that bridge when I get to it.
The major problem right now is that I'm still waiting on the production GPUs. The system as proposed does not work terribly well without a large number of GPU cores to run tasks on, and right now, I have a single 8800GTX in the system. This is a problem, when the concept is designed around 3 GTX295s (6 GTX280-ish cores).
I made some good progress on the web interface last night. Hopefully I can continue that this weekend, but that depends on a lot of other things. :-/
