Bug 6371 Item Types description not properly displayed if not pure ASCII

In several places, C4::ItemType module is used to retrieve item types
and their description. If the description text contains non-ASCII
characters, those characters are not properly displayed.

This bug can be seen in:

  - 4xx plugin of a UNIMARC DB
  - Home > Admin > Item circulation alerts
  - others?...
