Flags from: util.cc

--fst_error_fatal: type = bool, default = true

FST errors are fatal; o.w. return objects flagged as bad: e.g., FSTs: kError property set, FST weights: not a Member() --ngram_error_fatal: type = bool, default = true NGram errors are fatal if true; otherwise returns objects flagged as bad: e.g., NGramModel::Error() is true

Flags from: weight.cc

--fst_weight_parentheses: type = std::string, default = ""

Characters enclosing the first weight of a printed composite weight (e.g., pair weight, tuple weight and derived classes) to ensure proper I/O of nested composite weights; must have size 0 (none) or 2 (open and close parenthesis) --fst_weight_separator: type = std::string, default = "," Character separator between printed composite weights; must be a single character
