"nvm could not be found" when user name has umlaut or non-ascii character

[heneds]

Issue:
After a fresh installation of nvm the application does not work but fails with the error message
"C:\Users_USERNAME_\AppData\Roaming\nvm could not be found or does not exist. Exiting."
This happens when USERNAME contains a non-ascii character. In the error message these characters are replaced with �.

How To Reproduce:

1. Create or use an Windows account with umlauts or non-ascii characters in the user name (and more importantly in the name of the user folder)
2. Install nvm.
3. If the installer asks to handle an existing node installation, answer yes
4. Run "nvm list"

Expected Behavior:
Expecting to see a list of node versions.

Workaround:
It works properly if you correct the path in settings.txt (while keeping the UTF-8 encoding)

Desktop:
Windows 11

Regarding the workaround: it's the "root" setting that needs correcting.

Which version of NVM4W are you using? There appears to be an issue in older versions of Go that misinterpret umlauts and other western European characters. I'm unclear whether these issues are fully resolved in more recent versions of Go.

[heneds]

I was using the latest version 1.1.9.

I can't find the installer version but it was created on December 15 at ‏‎20:11:50.

Thanks, v1.1.9 was created with Go 1.17, which is the latest stable release of Go. I'm unsure how to troubleshoot this at the moment since I do not have access to a German version of Windows. There is also a possibility this hasn't been fixed (or a reversion happened). I will look into this to the best of my ability, but I wouldn't count on an immediate resolution given the circumstance.

+1 from me - same issue seems to have occurred with a colleague with a Ç in his last name trying to install v1.1.9. We have not attempted older versions.

The version of Windows does not seem to be the issue (I believe he too is running on an English install) - it seems to be merely the path to the install location, in this case the username part. If I understand correctly, this should be reproducable by creating a new user (either "online" / MS account, or offline) with one or more "special" characters like those mentioned in the username. But I could be mistaken =)

Not stale AFAIK. (Looks like #744 is a recent duplicate.)

I didn't have this problem until after I upgraded to Windows 11 and upgraded NVM. It worked fine before upgrading to 1.1.9 but downgrading now doesn't help.

I got around this by opening C:\Users\Karl-JohanSjögren\AppData\Roaming\nvm\settings.txt and resaving the file as UTF8, so I'm guessing that it could have something to do with how the installer writes this file on Windows 11?

[coreybutler]

@karl-sjogren thanks for sharing. It could be the installer, but it could also be Windows 11 not respecting the file encoding (which should be UTF8 by default). It's a little difficult to tell while Windows 11 keeps receiving updates.

It sounds like encoding is the problem regardless of whether the content is read from the settings file or displayed as an error message.

Go 1.18 was just released and it looks like there may be a fix. I'll try building the next maintenance release on this to see if it resolves @heneds original issue. As for the installer, it hasn't changed in years (and works on American English editions), so I suspect something is going on with the Windows 11 encoding. Regardless, I will look into this when I get a chance to build the next update.
