How to Remove Unicode Characters in Python [4 Examples]

In this Python tutorial, we will discuss how to remove unicode characters in Python in detail.

Unicode characters are essential for encoding text in various languages and scripts, allowing for the representation of diverse writing systems.

However, there are instances where we may need to remove Unicode characters from a string in Python, such as when working with data that requires ASCII encoding or when cleaning text for analysis.

As we are discussing how we can remove unicode in Python, we will discuss the following scenario-based examples mentioned below:

  • Remove Unicode characters from the string Python.
  • Python remove Unicode ” u ” from string.
  • Remove special characters in Python string.
  • Remove non-ASCII characters in Python.

How Python remove unicode characters from text

In Python, to remove the Unicode characters from the string Python, we need to encode the string by using the str.encode() method for removing the Unicode characters from the string.

The encode() method is used to encode a string into a sequence of bytes, typically representing the Unicode encoding of the characters in the string.

Here is an example:

string_unicode = " Python is easy \u200c to learn. "
string_encode = string_unicode.encode("ascii", "ignore")
string_decode = string_encode.decode()
print(string_decode)

After writing the above code (remove Unicode character from string python), Once you print “string_decode,” then the output will appear as a “Python is easy to learn.” Here, encode() is used to remove the Unicode from the string in Python.

You can refer to the screenshot below for removing Unicode characters from string python.

Python remove Unicode “u” from the string

In Python, to remove the Unicode ” u ” character from the string then, we can use the replace() method.

The replace() method in Python is a string method used to create a new string by replacing all occurrences of a specified substring with another substring.

Consider the following example:

string = "u\'Python is easy'"
string_unicode = string.replace("u'", "'")
print(string_unicode)

After writing the above code (Python removes Unicode ” u ” from a string), Once we print “string_unicode,” then the output will appear as a “Python is easy.”

Here, this removes the Unicode ” u ” from the string in Python.

Refer to the screenshot below for removing the Unicode ” u ” from the string Python.

We can also use Python to remove the Unicode ” u ” character from the string by using the encode() method, and here ” u ” is Unicode, which is removed with something else.

Here’s a simple example:

string = u'hello world!'
string_encode = string.encode('ascii')
print(string_encode)

After writing the above code (Python remove Unicode ” u ” character from a string), Ones you will print “ string_encode,” then the output will appear as a “ b’hello world!”. Python removes the Unicode ” u “ character from the string with something else.

Refer to the screenshot below for removing the Unicode ” u ” character from the string python.

Remove unicode characters from string in Python

In Python, for removing special characters in Python string, we use the isalnum() method for removing special characters from a string. Special characters can be whitespace, punctuation, or slash.

The isalnum() method in Python checks if all the characters are alphanumeric, like alphabet letters (a-z) and numbers (0-9).

Let’s see an example:

my_string = "sgr /k !? 100002"
string = ""
for character in my_string:
if character.isalnum():
string = string + character
print(string)

After writing the above code (remove special characters in python string), Once we print “string,” then the output will appear as an “sgrk100002”.

Python removes the special character from the string, and it will return a string with letters and numbers, and the loop will iterate through each character.

Refer to the screenshot below for removing special characters in a Python string.

This is how we can remove special characters in Python strings.

Remove non-ASCII characters in Python

To remove non-ASCII characters from a string in Python, we need to use string.encode() with encoding as ASCII and error as ignore. To return a string without ASCII characters, use string.decode().

For instance:

string_nonASCII = " àa fuünny charactersß. "
string_encode = string_nonASCII.encode("ascii", "ignore")
string_decode = string_encode.decode()
print(string_decode)

After writing the above code (remove non-ASCII characters in Python), Once we print “string_decode,” then the output will appear as “funny characters.”

The encode() function is used to remove the non-ASCII characters from the string, and the decode() function will encode the string in Python.

You can refer to the below screenshot for removing non-ASCII characters in Python.

Conclusion

I hope you understand all the examples to remove Unicode characters in Python taken in this article, and I have used different methods in each example to explore Python like the str.encode() method, replace() method, isalnum() method, and encode() with decode() methods.
