Title:
  UnicodeEncodeError when creating user with non-ascii chars

Status in cloud-init:
  Confirmed
Status in subiquity:
  New
Status in cloud-init package in Ubuntu:
  Fix Released

Bug description:
  I was testing subiquity, and at the user creation prompt typed in
  "André D'Silva" for the username, and just "andre" for the login.

  The installer finished fine, but upon first login I couldn't login.
  Booting into rescue mode showed me that the user had not been created.

  Checking cloud-init logs, I find the UnicodeEncodeError.
