Version: (using KDE 4.2.0) Installed from: Ubuntu Packages There is currently no way to enter Unicode character codes in KDE. In Gnome one can enter Unicode characters with Ctrl-Shift-U-unicodeNumber, and Windows and OS-X have similar conventions. Currently, KDE users must know in advance which Unicode characters they might need and configure them in KcharSelect ahead of time. And since there is no way of typing the characters, the user must copy and paste them from another application into KcharSelect.
Dotan beat me to filing this. Also, see ISO 14755. I am kind-of surprised that i18n requirements haven't already forced implementation of this feature. It does seem overdue.

Thanks, Tristan, you are right. Marking. *** This bug has been marked as a duplicate of bug 103788 ***
There is another workaround: configure your keyboard map via X.org's xkb. This is useful for assigning keys (or key combinations) to commonly used Unicode characters. However, it's not so useful for one-off entry of arbitrary symbols.
