UTF-8 problem in TCC related to Python


I have the following test-script in Python, encoded in UTF-8:

# encoding: utf-8

# Set the console codepage for this script to UTF-8
# Shouldn't be necessary through the 1st line: #encoding: utf-8
#os.system('chcp 65001')

print("jö, jä, jü")
print(u"jö, jä, jü")

After I open the Command Prompt, I can direct run the PY file OR with "python" at beginning without any problems with german umlauts, see here ...

However, if I try the same within TCC console, I HAVE the following problem after direct run the PY file (no problems with "python" at beginning) ...

Can somebody help me with this problem (Rex?)?


PS: System data: Microsoft Windows 10 Pro x64 [18363.836] [1909] TCC 26.01.40 x64, Python 3.8.3 x64
PPS: I have NOT enabled the Unicode output and UTF-8 option for TCC. Also if I change the codepage to 65001 manually (or with the Python programm (with "os.system('chcp 65001')") it does not change anything. BTW: I KNOW that the "u" in python print command is deprecated since a while, I also know that the first line with "# encoding: utf-8" is not good style (if file is in utf-8 in Python 3.x) - it's just for testing purposes).

No, it run always in "pure 1252" CP TCC window, except when I had changed for testing (which was even also not successful). That's a weird thing, because the call with "python program.py" does work ... I assume, this COULD be a specifiy problem with the call of the related DLL of python somehow (which runs over Command Prompt and does not work over TCC) ...

PS: Same result also with the Windows MAY update (Microsoft Windows 10 Pro x64 [19041.264] [2004] TCC 26.01.40 x64)

PPS: YES, the call of the python DLL (core) seems the reason. I saw, that the Command Prompt does start the python.exe instead loading the python core via DLL and then it runs without problem!

So, after I deactivated the Python Script language in the TCC options, it runs without problem too! Unfortunately, the autocompletion for py files is now also gone ...

Rex, is this problem with loading the Python Core DLL a Python problem or a TCC problem? OR, could you make a workaround?

Just a question - if it's not possible it's not the end of the world.
