X does not allow input of Unicode characters using Ctrl+Shift followed by the character code

There is currently no way to enter Unicode character codes in X. Some downstream implementations, such as Gnome, have implemented this independently. However, others such as Qt and KDE are waiting for a native X implementation. Currently, X users must copy and paste non-letter unicode characters from application to application.
