Pycharm: UnicodeDecodeError: 'utf-8' codec can't decode byte 0xce in position 1023
07:25 03 Apr 2026

When I use Pycharm's debugger and I inspect a dictionary in the debug window, if there are characters in the dictionary which are somewhat unusual, (Greek, for example), sometimes the debugger will crash, yielding the following error message:

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xce in position 1023: unexpected end of data

From my research I've learned that possible the cause is that the characters use a lot of memory and pycharm sets a limit which is 1024 bytes. i've tried to increase the byte length with the following hack:

os.environ['PYDEVD_MAX_STRING_LENGTH'] = 70_000

try:
    import pydevd
    pydevd.MAX_STRING_LENGTH = 30000
except ImportError:
    p ('debugger not attached')
    pass # Debugger isn't attached yet

But I'm still getting the same error. I've been suffering from this error now for about 2 years and have contacted Pycharm numerous times about it and they are aware of it but they don't care about the issue.
