If you are a Python programmer, it is highly likely that you have come across the dreaded UnicodeEncodeError. It often appears when you are using the urllib.request module to fetch web pages from non-English websites. The error message reads ‘ascii’ codec can’t encode character ‘\xe9’.
This error occurs because the ASCII codec, which is the default encoding for Python 3, cannot handle non-ASCII characters like é, á, or ñ, which are commonly found in languages other than English. When you try to encode these characters into ASCII, you’ll get the UnicodeEncodeError.
If you are facing this issue, don’t panic, there’s a solution. You need to change the encoding to UTF-8, which can handle all kinds of characters, including non-ASCII ones. This will ensure that your Python program can fetch and handle web pages from any site in any language.
To learn how to fix the UnicodeEncodeError in Python with urllib.request, read on. We’ll show you the exact steps to take to get rid of the error and make your Python program more robust and versatile.

Comparison of UnicodeEncodeError: ‘ascii’ codec can’t encode character ‘\xe9’ in Python3 urllib.request
Introduction
Python is one of the most preferred programming languages among developers. It is used in various fields, from web development to scientific computing. However, while working with Python, you might come across errors that can be quite frustrating. One such error is UnicodeEncodeError: ‘ascii’ codec can’t encode character ‘\xe9’ when using the urllib.request module in Python 3.In this article, we will discuss the reasons behind this error and compare different approaches to fixing it.
Understanding the Error
The UnicodeEncodeError: ‘ascii’ codec can’t encode character ‘\xe9’ error usually occurs when Python fails to encode a non-ASCII character in a string into ASCII. The \xe9 character represents the é character, which is a non-ASCII character.Python’s default encoding is ASCII, which only covers characters in the ASCII character set. Therefore, when Python encounters a non-ASCII character, it tries to convert it into ASCII, resulting in a UnicodeEncodeError.
The Problem with the urllib.request Module
The urllib.request module is a library for opening URLs. However, when opening a URL with non-ASCII characters using urllib.request, Python tries to convert the non-ASCII characters into ASCII, resulting in a UnicodeEncodeError.
Comparing Different Approaches
There are several ways to fix the UnicodeEncodeError when using urllib.request. Let’s compare some of the popular approaches.
Approach 1: Using the Requests Library
One of the most popular solutions to the UnicodeEncodeError is to use the requests library instead of urllib.request. The requests library handles non-ASCII characters by default and does not raise any UnicodeEncodeError.Here’s an example of how to use the requests library:“`import requestsurl = https://example.com/éresponse = requests.get(url)“`
Approach 2: Setting the Default Encoding
Another approach is to set the default encoding to UTF-8 using the sys module.Here’s an example of how to set the default encoding to UTF-8:“`import sysif sys.stdout.encoding != ‘utf-8’: sys.stdout = codecs.getwriter(‘utf-8’)(sys.stdout.buffer, ‘strict’)“`
Approach 3: Manually Encoding the URL
You can also manually encode the URL using the urllib.parse module.Here’s an example of how to manually encode the URL:“`from urllib.parse import quoteurl = https://example.com/éencoded_url = quote(url, safe=’:/?&=’)“`
Conclusion
In conclusion, the UnicodeEncodeError: ‘ascii’ codec can’t encode character ‘\xe9’ error occurs when Python fails to encode a non-ASCII character into ASCII. When using the urllib.request module, Python tries to convert non-ASCII characters into ASCII, resulting in a UnicodeEncodeError.To fix this error, you can switch to another library like requests, set the default encoding to UTF-8 using the sys module, or manually encode the URL using the urllib.parse module. It is recommended to choose the approach that suits your needs and coding style.
Thank you for visiting our blog on UnicodeEncodeError in Python3 urllib.request. We hope you found the information we provided to be informative and helpful. While this error can be frustrating, it is an important issue to understand and handle properly during coding.
As we mentioned in the article, the error occurs when attempting to encode non-ASCII characters using the ‘ascii’ codec in Python3. This is because ASCII only includes 128 characters and cannot represent all characters used in different languages and scripts worldwide. Therefore, it is essential to use the correct encoding type that supports the characters you need to work with.
We understand that coding can be a complex process, and it’s not uncommon to come across errors like the UnicodeEncodeError. That’s why we highly recommend familiarizing yourself with Python3’s encoding methods, as well as other best practices for debugging and troubleshooting errors. With that in mind, we hope our article has been a helpful resource for you, and we wish you the best of luck in your future coding endeavors.
People Also Ask about UnicodeEncodeError: ‘ascii’ codec can’t encode character ‘\xe9’ in Python3 urllib.request:
- What is the cause of this error?
- How can I fix this error?
- Are there any alternative solutions to this problem?
- Is this a common issue with Python3 urllib.request?
Answer:
- The cause of this error is that the ‘ascii’ codec cannot encode certain characters such as ‘\xe9’, which is a unicode character for é.
- To fix this error, you can use the .encode() method to convert the string to a byte string before passing it to urllib.request. For example, instead of passing the string directly like this:
url = https://www.example.com/é, you can encode it like this:url = https://www.example.com/é.encode('utf-8') - Another alternative solution is to use the unquote() method from urllib.parse to decode the url before passing it to urllib.request. For example:
from urllib.parse import unquote
url = unquote(https://www.example.com/%C3%A9) - Yes, this is a common issue when working with non-ASCII characters in Python3 urllib.request.
