There have been sufficiently enough console programs throughout my Linux 
life that I have come to regard only certain control sequence as 
reliable, and ^U is not amongst these.

Midnight Commander rebinds ^U to swap panels,
gpg2/pinentry-ncurses takes ^U verbatim,
nano and editors of that family make ^U a paste rather than a kill,
(re)(al)pine and MUAs of that family inherit nano behavior.

The reliable sequences I mentioned... just ^C, and surprisingly ^D.
And maybe ^S, because that always interferes when you least expect it :-)
