Describe the bug

A clear and concise description of what the bug is.

Steps/Code to reproduce bug

I'm seeing the following error.

File "/usr/local/lib/python3.10/dist-packages/nemo_text_processing/text_normalization/normalize.py", line 172, in __init__
  self.tagger = ClassifyFst(
 File "/usr/local/lib/python3.10/dist-packages/nemo_text_processing/text_normalization/fr/taggers/tokenize_and_classify.py", line 85, in __init__
  self.whitelist = WhiteListFst(input_case=input_case, deterministic=deterministic, input_file=whitelist)
 File "/usr/local/lib/python3.10/dist-packages/nemo_text_processing/text_normalization/fr/taggers/whitelist.py", line 44, in __init__
  graph = _get_whitelist_graph(input_case, get_abs_path("data/whitelist.tsv"))

 File "/usr/local/lib/python3.10/dist-packages/nemo_text_processing/text_normalization/fr/utils.py", line 41, in load_labels
  labels = list(csv.reader(label_tsv, delimiter="\t"))
 File "/usr/lib/python3.10/encodings/ascii.py", line 26, in decode
  return codecs.ascii_decode(input, self.errors)[0]
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe1 in position 1: ordinal not in range(128)

The issue is similar to this: #3452

Expected behavior

The expected behavior is to load without an error.
