It was found that when Cumin was asked to display a link name that contained non-ASCII characters, it would exit with an error and not display the content of the page with the link in it. Due to incomplete support for Unicode, if an administrator were to add data to the database (via Cumin or Wallaby, among others) that contained non-ASCII characters, subsequent requests to load data containing these characters would result in unexpected termination of the Cumin request, and the requested page would not be displayed.

IssueDescription: It was found that if Cumin were asked to display a link name containing non-ASCII characters, the request would terminate with an error. If data containing non-ASCII characters were added to the database (such as via Cumin or Wallaby), requests to load said data would terminate and the requested page would not be displayed until an administrator cleans the database.
