LibIndic's Payyans module may be used to convert texts encoded in ASCII format
to Unicode and vice-versa. More fonts can be added by placing their maps in
libindic/payyans/maps folder.
python -m pip install -e 'git+https://github.com/libindic/payyans.git#egg=libindic-payyans'
from libindic.payyans import Payyans
instance = Payyans()
result = instance.ASCII2Unicode("aebmfw", "ambili")
print(result) # മലയാളം
result2 = instance.Unicode2ASCII(u"കേരളം", "ambili")
print(result2) # tIcfw
instance.listAvailableMaps() # Haritha, ML-TTAmbili, ML-TTKarthika, ML-TTNandini, ML-TTRevathi, MLB-TTIndulekha, Manorama, Matweb, TM-TTValluvar, banglapedia, charaka, panchari, revathi, uma
instance.printMap('Haritha') # prints the whole mapping file
