If " •" ("don't") and " †" (past tense marker) are correctly recognized as two words, we may predict the previously unseen characters "g " ("tell spoilers") as an informal word, based on the learned Chinese language patterns.
state-of-the-art Chinese segmenters 1 incorrectly yield " • g †", preferring to chunk " †" ("thoroughly") as a word, as they do not consider the possibility that "g " ("spoiler") could be an informal word.
