Use currently saved settings on logon screen fails with non-ASCII username

Using a Microsoft Surface Pro. In Preferences > General settings, when selecting "Use currently saved settings on the logon and other secure screens" button, the UAC opens and when "Yes" is selected, the following error is returned:

"Error copying NVDA user settings".

Please reproduce the problem and then provide a log file as explained in ReportingIssues#ProvidingLogFiles. You'll need to set the log level to input/output.

Uploaded the log file. I didn't receive an email update to the ticket though, so adding in this comment just in case.

I'm guessing you have non-ASCII characters in your username (i.e. the é in Léonie)?

Technical: When we elevate to set the system config, slave gets the arguments from sys.argv, but sys.argv is ANSI in Python 2.x. Arrrg! We need this in Unicode. I guess we can decode using mbcs, as the username is hopefully in the system code page. Alternatively, we could retrieve the command line arguments using Windows Unicode functions, though I'm not sure where we'd put this code.

Thoughts, Mick?

in tryCopyFile, I believe we should decode sourcePath and destPath from mbcs to unicode if they are indeed ansi. This is of course before we try to prepend the back slashes. Interestingly tryRemoveFile does not have the issue as we seem to use MovefileA specifically if its not unicode. For tryCopyFile though I think its shorter to correctly decode rather than trying to use both A/W functions all the way down.

Fixed this specific situation in a290a16. In the end the changes were made in nvda_slave and config._setSystemconfig rather than touching install.tryCopyFile.
