How Can I Remove Accents from Unicode Strings in Python?

Remove Accents (Normalize) in Python Unicode String

Removing accents (diacritics) from a Unicode string involves converting it to its long normalized form, where letters and diacritics have separate characters. Subsequently, diacritic characters are removed to obtain the desired normalized string.

Using the Python Standard Library

Unfortunately, the Python standard library does not provide a direct solution for accent removal in Unicode strings. However, you can use the unicodedata module to obtain character information and modify the string accordingly.

Using Third-Party Libraries

For a more convenient and comprehensive solution, third-party libraries like pyICU can be employed. Here's an example using unidecode:

import unidecode

accented_string = 'kožušček'
normalized_string = unidecode.unidecode(accented_string)

print(normalized_string)  # Output: 'kozuscek'

Implementation Details

unidecode transliterates Unicode characters into their closest ASCII equivalents. It utilizes an extensive mapping table to convert accented characters to their base forms. Unlike explicit mapping approaches, it handles a wide range of Unicode characters, including those not commonly used.
