VisualEditor character map not available in dialogs
Open, LowPublic

Description

VisualEditor has a charmap tool but it's only available in the main window, not in dialogs. The specific case where this came up was entering a file name with a special character in the media selector interface, but there are many other dialogs where this might be a problem.

It would be nice to have a charmap tool that's integrated into dialogs by default (or maybe into the jQuery IME interface).
