Reproduction steps:
1- Create an account with a username containing a character such as 'ß'
2- Start Unity from that account

Expected Result:
Editor should be able to talk to Unity.Licensing.Client if username has special characters.

Actual Result:
Editor cannot talk to Unity Licensing Client if user name has Unicode characters.

Although this was reported in closed network but it should be applicable in open network.

Success Criteria:

Editor can talk to licensing client if user name has special characters.

Implementation Notes:

Normalize the username and pass to Client.
Default Licensing Client user name extraction should be same as the one that editor uses.
Environment: Windows
