Azure Function Python String Encoding Issue

I am having an issue with an Azure Function in Python.

The following code:

test = b'\xce\x94'
print(test)
a = test.decode('utf-8')
print(a)

prints the following if I run it in Python 3.9 on my PC running Windows 10.

b'\xce\x94'

Δ

This is correct as it should result in the Delta character.

If I run the same code in an Azure Function App (also Python 3.9) it errors if I try to print it

System.Private.CoreLib: Exception while executing function: Functions.HttpTrigger. System.Private.CoreLib: Result: Failure
Exception: UnicodeEncodeError: 'charmap' codec can't encode character '\u0394' in position 0: character maps to <undefined>

    return codecs.charmap_encode(input,self.errors,encoding_table)[0]

or shows a

?

if I log it using Python logging library.

Can anyone help please?
