From the man page for tcsh:
12. NEW PROMPT FORMAT
The format for the prompt shell variable has been changed to
include many new things, such as the current time of day,
current working directory, etc.. The new format uses
"%<char>" to signal an expansion, much like printf(3S). The
available sequences are:
[...]
%U (%u) Start (stop) underline mode. (Only if
tcsh was compiled to be eight bit clean.)
[...]
\c `c' is parsed the same way as in bindkey.
^c `c' is parsed the same way as in bindkey.
and
In strings control characters may be written as caret-
<letter> and backslash ("\") is used to escape a character
as follows:
\a bell character
\n line feed (new line)
\b back space
\t horizontal tab
\v vertical tab
\f form feed
\r carriage return
\e escape
\nnn character code in octal
