Convert Arabic glyphs into standard letters

[linuxscout]

According to previous issue issue 57, we propose to add a new function to unshape this text

Salam,
I tested the given words with pyarabic word as follow,
the word contains encoded glyphs not standard letters, it must be converted to ordinary letters.

To convert glyph based word into a string of letters you can use:
NB: the second unshape function is used only to inverse the result word

 word = "ﻣﺴﺎﻣﻌﻬﻢ"
 from pyarabic.unshape import unshaping_word
unshaping_word(unshaping_word(word))
'مسامعهم'

• The test used to detect the problem

``>>> import pyarabic.araby as ar

lst=["اﻟﻤﺴﺌﻮﻟﻴﺔ","ﻣﺴﺎﻣﻌﻬﻢ","ﻓﻜﻠﻨﺎ","ﻣﺒﺎدراﺗﻨﺎ","ﻓﻬﻢ","اﻟﻤﻨﻈﻮﻣﺔ"]
for i in lst:
... print(i, ar.is_arabicword(i))
...
اﻟﻤﺴﺌﻮﻟﻴﺔ False
ﻣﺴﺎﻣﻌﻬﻢ False
ﻓﻜﻠﻨﺎ False
ﻣﺒﺎدراﺗﻨﺎ False
ﻓﻬﻢ False
اﻟﻤﻨﻈﻮﻣﺔ False

for i in lst:
... print("%s"%i, ar.is_arabicword(i))
...
اﻟﻤﺴﺌﻮﻟﻴﺔ False
ﻣﺴﺎﻣﻌﻬﻢ False
ﻓﻜﻠﻨﺎ False
ﻣﺒﺎدراﺗﻨﺎ False
ﻓﻬﻢ False
اﻟﻤﻨﻈﻮﻣﺔ False
for i in lst:
... for c in i :
... print(c, ord(c), ar.name(c))
