Can not reproduce the example

[JohnHerry]

Thanks for the job.

I have download the mandarin cedict file and tried the example code

`from epitran.backoff import Backoff

backoff = Backoff(['hin-Deva', 'eng-Latn', 'cmn-Hans'], cedict_file=‘cedict_1_0_ts_utf-8_mdbg.txt')
backoff.transliterate('हिन्दी')
'ɦindiː'
backoff.transliterate('English')
'ɪŋɡlɪʃ'
backoff.transliterate('中文')
'ʈ͡ʂoŋwən'`

But when I use backoff to transliterate an English word, It raise Exception:

"""
arpa_text = arpa_text.splitlines()[0]
Index out of range
"""

When I input Chinese, it can convert output of the form PinYin but not IPA.

How to make IPA output when my input is a sentence of bilingural-English-Chinese characters?
