svn2git failing saying Author: VisualSVN Server not defined in ./authors.txt file

Just ran into this. For svn2git, you'll need to add a line in your Authors file like follows:

VisualSVN Server = Visual SVN Server <[email protected]>

The solution that worked for me: Encoding of the authors-transform file on Windows must be "UFT-8 without BOM".

Just use some smart editor that can do the convertion.
