Portal username should allow for apostrophes

Idea created by hrastche on Feb 9, 2016
    Portal for ArcGIS 10.3.1 does not allow for the username to contain an apostrophe. This makes it hard for people of Irish and Scottish origin who have apostrophes in their usernames and emails: e.g. KO’Connell@acme.com
    Please think about the Irish and the Scots and allow apostrophes in usernames and names on Portal for ArcGIS.
