the TypeError: decoding Unicode is not supported in Python

A Unicode string is a collection of code points, which are digits ranging from 0 to 0x10FFFF (1,114,111 decimal). The set of code units that must be used to represent this series of code points in memory is then mapped to 8-bit bytes.

A character encoding, or simply an encoding, is a set of rules determining how to convert a Unicode text into a series of bytes. Your initial thought could be to use 32-bit integers as the coding unit and then to use the CPU’s representation of 32-bit integers.

One of the most widely used encodings is UTF-8, which Python frequently uses by default. UTF stands for Unicode Transformation Format, and 8 indicates that the encoding uses 8-bit values.

There are other encodings, such as UTF-16 and UTF-32, although they are less popular than UTF-8.

Example Code:

result = unicode(google.searchGoogle(param), "utf-8").encode("utf-8")

Output:

TypeError: decoding Unicode is not supported

Fix the TypeError: decoding Unicode is not supported in Python

To solve this error, we have to change syntax of this line result = Unicode(google.searchGoogle(param), "utf-8").encode("utf-8") to result = google.searchGoogle(param).encode("utf-8"). UTF-8 should be removed after google.searchGoogle(param) .so this will solve the error decoding Unicode is not supported, as shown in the below example

result = google.searchGoogle(param).encode("utf-8")

Another is the TypeError: decoding str is not supported in Python. This occurs when we repeatedly try to convert an object to a string or when we call the str() method without first passing it bytes object.

Example Code:

str('even', str(123))
str('abc', encoding='utf-8')

Output:

TypeError: decoding str is not supported

The str class is referenced twice in the above example; each call is nested within the other. A proper bytes object is not provided; instead, the encoding keyword argument is set.

Only when a valid bytes object is given can the encoding be configured.

To avoid this error, you can use a formatted string literal. This error can be prevented using the string format interface or the more recent formatted string literals.

Additionally, these options offer more potent, adaptable, and extendable methods.

str1 = 'even'
num1 = 2,4,6,8
result = f'{str1} {num1}'
print(result)

Output:

even (2, 4, 6, 8)

Conclusion

Sometimes when we want to encode our output to UTF-8 but we are not using the right syntax, the error Python decoding Unicode is not supported arises because a correct bytes object is not supplied. Another error decoding str is not supported in Python occurs.

Only when a valid bytes object is provided can the encoding be defined. The above article fixes these errors.
