Component and Version are not displayed properly. See attached screenshots.

We've tested with the following combinations of JIRA and Confluence versions and we saw the reported problem shown by attached image of 'bandicam 2012-05-15...' in all of them.

We did the test you said and the results are attached. The JIRA-Confluence versions of this test is 5.0.4-4.1.9. As you can see in the screen shots, most of the language display works fine. This problem is, I guess, specific to the pop-up screen of Insert-JIRA-Issue.

The JIRA's Component and Version are not displayed properly. Project name and Task type are properly displayed. Concerning the screen shot, we defined two Components in JIRA for test purpose. One of the components have Japanese characters in its name and the other had no Japanese character.

It is sure that Versions, if name has Japanese characters, are not displayed properly in similar way as Components does not.
