why we hardcoded in here?


graph_digit = pynini.string_file(get_abs_path("data/numbers/digit.tsv"))

NEMO_TA_DIGIT = pynini.union("௦", "௧", "௨", "௩", "௪", "௫", "௬", "௭", "௮", "௯").optimize()

we have numbers/digit.tsv why we need additional NEMO_TA_DIGIT?

graph_digit = pynini.string_file(get_abs_path("data/numbers/digit.tsv"))

NEMO_TA_DIGIT = pynini.union("௦", "௧", "௨", "௩", "௪", "௫", "௬", "௭", "௮", "௯").optimize()
TAMIL_DIGIT = ["௦", "௧", "௨", "௩", "௪", "௫", "௬", "௭", "௮", "௯"]
