Avoiding selection in quail

Avoiding selection in quail

[Douglas Lewan]

I'd like to add "|N" --> "ℕ" (among a few others) to latin-1-prefix:

(with-temp-buffer
   (set-input-method 'latin-1-prefix)
   ...
   (quail-defrule "|N" "̱ℕ")
   ...))

When I type "|N" quail gives me a list to choose from. I know that in 
previous lives that hasn't happened. Can someone help my understand what 
I'm doing wrong?

I'm running emacs 24.5 on Debian 9.4.0. (My first thought was that 
Debian might have messed with something related, but I've gone through 
the Debian-specific emacs lisp, but I didn't find anything.)

Thanks.

What kind of "list" is that?  Please show what you see in the echo
area after typing | and after typing N that follows.

Also, it could be that the other rules you added are relevant, so
please show them all.

In general, if Emacs shows several possible sequences, it means what
you typed is ambiguous and can be the beginning of more than one full
sequence.

Your translation string consists of two characters, the first being
U+0331 COMBINING MACRON BELOW, the second U+2115 DOUBLE-STRUCK CAPITAL
N. quail-defrule’s docstring says each character becomes a translation
candidate.

Here's what I see in the echo area:
     |N     (01/01) 1.̱ 2.ℕ
(Well, that's my rendition. I couldn't figure out how to capture the 
echo area. A corresponding image is attached.)

This sounds good and pointed me in the right direction. I shouldn't have 
been using strings as targets of quail rules; I should have been using 
characters (and I do now). That explains the ambiguity that Eli mentions.
Touching an input method is not something you do very often, so I'm not 
surprised I forgot a detail. Things look good now.
Thanks to both of you for the help.
