Can `Memory::dict_` be `NULL` ?

dict_.reset(dictionary->Create(ticket));

Shouldn't be a null pointer as it is assigned an instance of Dictionary in the constructor.
But the Dictionary may not be loaded.

I think Memory::dict_ can be NULL, but I'm not sure if it will happen in reality.

The Create() function may return nullptr:

librime/src/rime/dict/dictionary.cc

Line 368 in 7d9ad77

Dictionary* DictionaryComponent::Create(const Ticket& ticket) {

And there is a check before Load():

librime/src/rime/gear/memory.cc

Line 56 in 7d9ad77

if (dict_)

you are right. the case dict_ is null should be handled.
