i am trying to write a python program that prints music notes (like -> u1d15e). However, i cant quite get it to work.

Here is what i get using the following code

note = '\U0001d15e'
bytes = note.encode('utf-8')
print(bytes)

>>> b'\xf0\x9d\x85\x9e'

If i try to print the string directly i get

note = '\U0001d15e'
# bytes = note.encode('utf-8')
print(note)

Traceback (most recent call last):
  File "c:\___\___\___\file.py", line 34, in <module>
    print(note)
  File "C:\Users\user\AppData\Local\Programs\Python\Python310\lib\encodings\cp1252.py", line 19, in encode
    return codecs.charmap_encode(input,self.errors,encoding_table)[0]
UnicodeEncodeError: 'charmap' codec can't encode character '\U0001d15e' in position 0: character maps to <undefined>

I am not sure what the problem is. I know that similar questions have been asked before, however the proposed solution did not work for me. Thank you for your help in advance :)

i am using python 3.10.4

  • When I run `print(note)` in IDLE I get a question mark which indicates that the font can't handle the code point, but I don't get any error. – John Coleman Nov 24 '22 at 15:00
  • The short version is that this is a Windows problem (more specifically, a `cmd.exe` problem) that doesn't really have anything to do with Python, and you may or may not be able to do anything about it, depending on the character. – Karl Knechtel Nov 24 '22 at 15:06
  • Thank you for the answer, the problem was my windows console was not set to utf-8 – vreithinger Nov 24 '22 at 21:58

My system doesn't like that representation either, but can directly put it into a string and print() it

To me, this is some artifact of your system being Windows and you need to set your console to use UTF-8 instead of cp1252

Using UTF-8 Encoding (CHCP 65001) in Command Prompt / Windows Powershell (Windows 10)

>>> "" == "\U0001d15e"
True
>>> note = ""
>>> note.encode()
b'\xf0\x9d\x85\x9e'
>>> print(note)
