I checked this and the reason for lsymbol appearing not to work as a
fallback is only that it uses "/" as a starter key. The documentation
for the fallback input method in /usr/share/m17n/global.mim says:

    (fallback-input-method
      (_"Fallback input methods.
    Value must be comma separated fallback input method names.
    When you type a key that is not handled by the currently activated intup 
method,
    fallback input methods (in the order specified in this variable) try
    to handle that key, and the first one that can handle the key is activated
    temporarily.
    For instance, as the default value of this variable is \"lsymbol, unicode\",
    when you type \"/...\" while you are activating an input method
    that doesn't handle that key sequence, \"lsymbol\" input method is activated
    and \"…\" (U+2026: HORIZONTAL ELLIPSIS) is inserted.")
      "lsymbol, unicode"))

So lsymbol can only work as a fallback in those input methods which do
*not* handle "/" already. And almost all input methods already do
something with "/", very few exceptions.

For example, in /usr/share/m17n/latn-pre.mim, "/" is used:


;; | dot above  |  . /   | .g -> ġ  /g -> ġ
;; | misc       |   /    | /a -> å  /e -> æ  /h -> ħ  /o -> ø  /oe -> œ
;; | misc       | " ~ /  | "s -> ß  ~d -> ð  ~t -> þ  /a -> å  /e -> æ  /o -> ø
..
;; | symbol     |   /    | /2 -> ½  /3 -> ¾  /4 -> ¼  /= -> ?¬
;; | symbol     |   /    | /# -> £  /$ -> ¤  /c -> ¢  /. -> ˙  // -> °  /\ -> ×


Therefore, lsymbol does not work as a fallback when latn-pre.mim is
used.

But, /usr/share/m17n/latn1-pre.mim does not use "/" at all. Therefore,
lsymbol works as a fallback when latn1-pre.mim is used.
