Keeping special chars in translations

Hi,
Translating applications texts, how can I keep special characters like \t ?:

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM,pipeline

# load model

tokenizer = AutoTokenizer.from_pretrained("facebook/nllb-200-distilled-600M")

model = AutoModelForSeq2SeqLM.from_pretrained("facebook/nllb-200-distilled-600M")

source="fra_Latn"

target="eng_Latn"

text = "\tCacher / Montrer ligne"

translator = pipeline('translation', model=model, tokenizer=tokenizer, src_lang=source, tgt_lang=target)

output = translator(text, max_length=400)

print(output)
