Comparing unicode characters with combining diacritics

Question

    Dictionary={
         "b":"कू", 
         "c":"कु",
         "x":"श",

         "A":"क"


def marathi(message):
    dec=''
    for letter in message:  
        for key, value in MARATHI.items():
             if letter == value:
               dec+=key
    print(dec) 



    returning_key_for_value_String='शकुकू'

    marathi(returning_key_for_value_String)
    #output=xAA

While running the function to get back the key from the values of a dictionary,the function is providing the key of "कू" as "A" , but it should be returning "b".It looks like the function is taking only "क", due to which the expected output is not coming.

Because you have composed characters in your string: `list('शकुकू')` gives `['श', 'क', 'ु', 'क', 'ू']` — Jan Wilamowski, Jul 20 '21 at 07:53
Does this answer your question?

@JanWilamowski How can iterate over it ,if i want them to be considered as one ,rather than two things — Rutvikk Walde, Jul 20 '21 at 10:08

You'll want to divide your string into grapheme clusters because it actually contains both letters and nonspacing combining marks:

>>> list('शकुकू')
['श', 'क', 'ु', 'क', 'ू']

The regex module can extract them via the \X pattern:

>>> import regex
>>> regex.findall(r'\X', 'शकुकू')
['श', 'कु', 'कू']

Then, you can compare each of these individual characters to your reference dictionary.
