Have you ever come across the Unicodedecodeerror: ‘Ascii’ codec. Ordinal out of range error while working with Python? It is a common error that occurs when Python fails to decode a byte and convert it into Unicode. This can be frustrating for developers who need to decode data from various sources.
The good news is that fixing this error is possible, and there are several ways to go about it. One way is to change the encoding of the data you are working with. Another approach is to use the encoding argument when opening files or using non-ASCII characters. You can also use the Unicode string format or ignore the problematic character. With these methods in mind, you can get your code up and running again without experiencing the same error.
If you want to learn more about how to fix the Unicodedecodeerror: ‘Ascii’ codec. Ordinal out of range error in Python, then continue reading! In this article, we will explain in detail the different causes of this error, as well as the different solutions you can choose from. Whether you are a beginner or an experienced Python developer, understanding how to fix this error is crucial to your success. So let’s dive in and start learning!
“Unicodedecodeerror: ‘Ascii’ Codec Can’T Decode Byte 0xd1 In Position 2: Ordinal Not In Range(128)” ~ bbaz
Introduction
When you encounter the UnicodeDecodeError: ‘ascii’ codec can’t decode byte X in position Y: ordinal not in range(128) error message, it can be quite frustrating to fix. Fortunately, there are different ways to solve this error, which we will explore in this article.
What is Unicode and ASCII?
Before diving into how to fix the UnicodeDecodeError, it’s essential to understand what Unicode and ASCII are. ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns a unique number to every letter, digit, and symbol on the keyboard. While ASCII is limited to only 128 characters, Unicode has a much broader scope, including more than 137,000 characters from various scripts worldwide.
What Causes the UnicodeDecodeError Error?
The UnicodeDecodeError is an error that occurs when Python tries to convert bytes into string objects and cannot detect the character’s encoding correctly. This error may happen when you try to read data encoded in a non-unicode format or read text written in a different encoding.
How to Fix the UnicodeDecodeError
Method 1: Use the Appropriate Encoding
One way to fix the UnicodeDecodeError is to use the appropriate encoding when reading and writing data. You can specify the encoding explicitly by calling the open() function with the ‘encoding’ parameter, such as:
with open(filename, 'r', encoding='utf-8') as f: # do something
Method 2: Ignore Errors When Reading Data
If you’re not sure about the file encoding, you can use the ignore or replace error handler to skip or replace invalid characters. Here’s how to ignore errors:
with open(filename, 'r', errors='ignore') as f: # do something
Method 3: Use the Chardet Library
The chardet library can help you detect the file’s encoding automatically. This library works by analyzing the text’s byte sequence and making an informed guess. Here is how to use chardet to detect the file’s encoding:
import chardet with open(filename, 'rb') as f: enc = chardet.detect(f.read()) with open(filename, 'r', encoding=enc['encoding']) as f: # do something
Method 4: Use Unicode Escape Sequences
If none of the above methods work, you can try using Unicode escape sequences to represent the non-ASCII character strings explicitly. Here’s how to use Unicode escape sequences:
text = Hello, \u00E4\u00F6\u00FC # do something with text
Comparison Table of UnicodeDecodeError Fix Methods
| Fix Method | Pros | Cons |
|---|---|---|
| Use the Appropriate Encoding | Guaranteed to work if the correct encoding is provided | Can be time-consuming to determine the encoding of the file |
| Ignore Errors When Reading Data | Allows you to skip invalid characters | May result in loss of data if invalid characters are essential |
| Use chardet Library | Faster way to detect encoding automatically | May misinterpret the file’s encoding and lead to errors |
| Use Unicode Escape Sequences | Works with any encoding | Can be challenging to read and write code with escape sequences |
Conclusion
The UnicodeDecodeError: ‘ascii’ codec can’t decode byte X in position Y: ordinal not in range(128) error message can be intimidating, but there are various ways to address it properly. Depending on the situation, you can use the right method to fix the error promptly. By understanding what causes this error, you can avoid it from happening in the future and help you write better Python code.

Here are some common questions people ask about the error message unicodedecodeerror: ‘ascii’ codec. Ordinal out of range and their respective answers:
-
What does the error message unicodedecodeerror: ‘ascii’ codec. Ordinal out of range mean?
The error message means that there is a character in your text that is not within the range of ASCII characters, which is causing the decoding process to fail.
-
Why am I getting this error message?
You might be getting this error message because you are trying to decode non-ASCII encoded text using the ASCII codec instead of the appropriate codec for the text’s encoding.
-
How do I fix the unicodedecodeerror: ‘ascii’ codec. Ordinal out of range error?
To fix the error, you can try one or more of the following solutions:
- Specify the correct encoding when opening the file or reading in the text.
- Use the appropriate codec for the text’s encoding.
- Replace the non-ASCII characters with ASCII characters.
- Ignore the non-ASCII characters using the errors=’ignore’ parameter.
