Issue Summary

If any project contains the non-ASCII character U+2028 in its name, the CSV External Import won't load any project names.

Character: https://www.compart.com/en/unicode/U+2028

This ticket is being opened in the MIG project for the following reasons:

• The component "Jira - Import - From External System" is configured in this project
• We should catch non-supported non-ASCII characters like the one causing this issue during site/project imports

Steps to Reproduce

1. Rename any project by adding the above character to the project name
2. Navigate to System > External System Import
3. Select CSV option
4. Upload a csv and click Next
5. Notice the project select doesn't list any options and typing any option manually displays "Invalid option"

Expected Results

Project names are displayed (regardless of a project name containing a non-supported ASCII character)

Actual Results

• Projects are not displayed in the project selector dropdown
  
• Error message

  batch.js?locale=en-GB:2296

Workaround

The workaround is to rename the offending project(s) and remove the unsupported character.

However, finding the projects is difficult as it requires database access, it's possible on Server/DC but not on Cloud: https://confluence.atlassian.com/jirakb/csv-importer-screen-does-not-list-any-projects-1005790911.html
