Special character in BTC core password not recognized

[trdiablo5]

Hello,

I suspect I had the special charachter ï in my password. So that is the letter i but with two dots on the i.
I have used the makefile file to add Unicode support. But when I run the btcrecoveru.py file I still get errors because the character ï is not recognized. below is the snipper of the CMD.

What can I do ? Please help?

What program did you use to create the tokU.txt file? When you save it, you must find the option to save it in UTF-8 format. In Windows Notepad, that option is just to the left of the Save button on the dialog box where you enter the name. Did you do this?

If this doesn't help, would you mind sending me a copy a tokU.txt file which causes this problem? You can remove anything in it which isn't causing a problem for privacy's sake. Let me know if you'd like to do this and I'll post back with instructions on how to send that file to me safely.

Hi Gurnec, thanks a lot for your reply. After reading your comment I have saved the Toku.txt file in UTF8 format (with Windows Notepad) and now it works. You are a genius, thanks again.

If I am able to find the password of my BTC wallet I will send you a reward. Word of honor.

I'm glad it's working! Good luck!

Hi Gurnec

I need some help and cannot find your rmail to email you directly. I know this post is old but im hoping that you will still check it. I have set up your program and its working great. I have a second GPU that i would like to add to my computer. In your GPU acceleration info you mentioned multiple GPU's. I went ahead and installed a second one but btcrecover is asking me to pick one it says --gpus names....is it possible to add multiple GPU's ? I have run the test and it sees both of them. I cannot figure out what the setting would be ? I have tried naming them but cannot figure it out. I have a GeForce GTX 1080 Ti and a GeForce GTX 1080 my info is below

cd C:\temp\btcrecover-master
C:\python27\python btcrecover.py --wallet wallet.dat --enable-gpu --global-ws 262144 --local-ws 1024 --tokenlist tokens.txt --no-dupchecks --no-eta --max-tokens 10 --typos 1 --typos-case --autosave savefile

thanks in advance

(this was answered elsewhere, but I'm copy-pasting it here for posterity)

By default, btcrecover only uses multiple GPUs at the same time if they're identical, but you can force it to use different GPUs if you'd like.

First, ask it for a list of your current OpenCL devices like so:

> C:\python27\python btcrecover.py --list-gpus
#1 GeForce GTX 1080 Ti
#2 GeForce GTX 1080
#3 Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz

It's easiest to specify the GPUs you want to use by the #ID numbers, so for example to use the two 1080s, even though they're different models:

> C:\python27\python btcrecover.py --enable-gpu --gpu-names #1,#2 ...

Note that you may get better performance if you use a different global-ws for each GPU (with a bigger global-ws for the Ti), something like this:

> C:\python27\python btcrecover.py --enable-gpu --gpu-names #1,#2 --global-ws 262144,196608 --local-ws 1024 ...

Note that the order matters: in this example, GPU #1 (the faster one) is listed first after --gpu-names, so the larger --global-ws is also listed first. Only way to know if using different global-ws values improves performance is trial and error unfortunately.
