Throwing aaransia.exceptions.SourceLanguageError when tried for transliterating Arabic to Tunusian.

[suhaneshivam]

I am trying to transliterate Arabic to Tunisian and getting the aaransia.exceptions.SourceLanguageError exception with almost every single sentence. This is what I have tried.

>>> from aaransia import transliterate, SourceLanguageError
>>> ar = "ﺎﻨﻫ ﻒﻋﻻ ﺵﺮﻓ ﻊﻈﻴﻣ ﻞﻳ ﺎﻧ ﺄﺼﻋﺩ ﺎﻠﻤﻨﺻﺓ ﻞﻠﻣﺭﺓ ﺎﻠﺛﺎﻨﻳﺓ. ﺄﻧﺍ ﻒﻳ ﻍﺎﻳﺓ ﺍﻼﻤﺘﻧﺎﻧ"
>>> transliterate(ar, source = "ar", target = "tn")
Traceback (most recent call last):
  File "/home/centos/.local/lib/python3.6/site-packages/aaransia/transliteration.py", line 103, in transliterate
    text.split())))
  File "/home/centos/.local/lib/python3.6/site-packages/aaransia/transliteration.py", line 102, in <lambda>
    return ' '.join(list(map(lambda word: _transliterate_word(word, source, target, universal),
  File "/home/centos/.local/lib/python3.6/site-packages/aaransia/transliteration.py", line 90, in _transliterate_word
    return u''.join(result).replace(u'\u200e', '')
TypeError: sequence item 0: expected str instance, NoneType found

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/centos/.local/lib/python3.6/site-packages/aaransia/transliteration.py", line 105, in transliterate
    raise SourceLanguageError(f'{SOURCE_LANGUAGE_EXCEPTION_MESSAGE}: {source}')
aaransia.exceptions.SourceLanguageError: Source alphabet language doesn't match the input text: ar

However, when tried with universal = True , I got the same sentence back. What is wrong?

>>> ar = "ﺎﻨﻫ ﻒﻋﻻ ﺵﺮﻓ ﻊﻈﻴﻣ ﻞﻳ ﺎﻧ ﺄﺼﻋﺩ ﺎﻠﻤﻨﺻﺓ ﻞﻠﻣﺭﺓ ﺎﻠﺛﺎﻨﻳﺓ. ﺄﻧﺍ ﻒﻳ ﻍﺎﻳﺓ ﺍﻼﻤﺘﻧﺎﻧ"
>>> transliterate(ar, source = "ar", target = "tn", universal = True)
'ﺎﻨﻫ ﻒﻋﻻ ﺵﺮﻓ ﻊﻈﻴﻣ ﻞﻳ ﺎﻧ ﺄﺼﻋﺩ ﺎﻠﻤﻨﺻﺓ ﻞﻠﻣﺭﺓ ﺎﻠﺛﺎﻨﻳﺓ. ﺄﻧﺍ ﻒﻳ ﻍﺎﻳﺓ ﺍﻼﻤﺘﻧﺎﻧ'

I think some Arabic alphabets are missing. What is the fix? Or I am doing something wrong?
